Well, for me mephedrone is much more social, I really feel like talking a lot. Not like amphetamine, but still. MDMA, on the other hand, is way more introspective for me, I usually just stand there doing some very repetitive dance (I dance way better on acid, booze or plain stimulants) and feeling awesome. I do feel the intimacy and love towards others, but I usually don't feel like talking and/or just don't get as social as with stimulants or alcohol. I even think amphetamine and also cocaine are much more fun than E, they don't feel as nice but are much more rewarding in the end because I get so sociable. I have taken amphetamine (actually fenproporex, N-(2-cyanoethyl)amphetamine, an anorectic that gets converted into amphetamine in rats and that was rather easily available for me for about a year) a bunch of times when going clubbing alone while travelling and end up meeting a bunch of people and having a lot of fun, a kind of fun that I remember later with much more satisfaction than I remember the moments while high on E.
The comedown from MDMA (or better said, pills) is way harsher, There is a 2h hour peak and then usually before the 3rd hour, although I'm still way off baseline for a few more hours, the bad feelings start most of the times. There's a quick, significant drop in effects, I get kind of uncomfortable, anxious and start chain smoking. Feels like my bubble of comfort suddenly bursted and I dropped a few meters into reality, I was surrounded by very friendly strangers just minutes ago but now when I look around I mostly see a lot of shady looking people. I start thinking - or craving- about dropping another one and usually do if I have it on me. My first real time on E I took 2 pills 1-2 hours apart, I had tried only one a previous time but they seemed too weak. I got very high, but this first stage of the comedown was maybe the worst I ever had.
Maybe that's related to a bad experience during the peak, in which a amped/coked up guy at the festival came over to me and started saying he was very high and was going to rob me or beat me up if I didn't follow him to the bathroom. I'm usually quite sensitive to aggressions but I felt quite confident and argued for a couple of minutes until a girlfriend of his came over and dragged him away, apologizing. That was a bit of a bummer, lingered on my mind for a while and made me a bit paranoid although I still felt great. Fifteen minutes later another guy - nice guy, retrospectively - came over just to chat but I got suspicious and didn't make much effort to keep the talk going so he eventually left. But by the end of the peak I had mostly forgotten that situation, and I wonder if anyone noticed that a bad experience can modify some effects or the comedown of E. So, during that comedown I remember wanting to go home and having thoughts like "I just got through the very peak of my life, what's it going to be like from now? What's the point of living past this experience..". After this stage of the comedown I feel better after 1-2h and still noticeably high. Not speedy at all anymore but quite comfortable, no social anxiety for hours (I normally have a little), quite a bit more talkative than at the peak and than my sober self. Eight hours after taking a pill, when getting home, I usually still feel some effects like increased sensitivity to the touch, increased feeling of focus (not real, I'm sure) and clearmindedness. Even some CEV appear, especially when I get to bed and close my eyes (no CEV on mephedrone, ever).
It's kind of like the MDMA stops working as a stimulant much earlier than it stops it's serotoninergic effects, giving me a harsher partial comedown. And maybe that first pill had something that further worsened the comedown. Anyone ever noticed something like that?
Such bad comedowns even got me bad emotional memories about some rave parties after my 10-15 experiences over 1,5 years. For example, I would randomly listen to some track (usually psytrance, the most popular thing here) and feel a growing sadness/angst, even though I could just barely remember ever hearing the track before. Then I would maybe remember a rave party, kinda like a flashback of coming down. That feeling would quickly subside after I would turn off the music. This feeling was more noticeable after I went to one party and took half a hit of acid plus 3 pills (at least fairly good), i think the acid made more sensitive to the comedown. I remember thinking a lot of fairly bad stuff, like "this is such an antisocial environment, specially now that a lot of people are probably coming down too; everyone is probably just too worried about their fading high and don't really give a shit about anything or anyone else". I guess I project my feelings on others and it seems there are lots of people around me distressed by their own comedowns. But I'm not sure it's just a delusion or a true realization. I worry about how the party is like a bomb waiting to explode with a big fight between irritable junkies, which is not entirely untrue in the mainstream psytrance parties that is filled with bitches and pumped up guys on steroid. I've seen a fight on 1/3-1/2 of the mainstream parties I've been to, but they usually happen already in the middle of the morning (maybe when the pumped up guys really come down after 10h eating pill after pill), not when I sometimes worry late in the night, and it is usually a small 1x1 that is quickly ended by the abundant security even though the guys seem so angry and ferocious doing jiu-jitsu on the ground after exchanging just a couple of punches that a circle of up to 15m of diameter may open up in like 5 seconds at a fairly crowded area. If everyone had a comedown like mine the parties would suck at some point. I never tell any of the people that are with me how I feel because I fear I would influence their high negatively, most don't seem to have this sort of comedown off the same pills. I once cautiously mentioned to my sister that I didn't feel very good, she seemed still quite high and gave me a hug that would feel great some time earlier but felt quite dull at this point with the rushes gone and the comedown taking over whatever all my thoughts.
All the differences I perceive between the two drugs might be very influenced by the place in which I take them. E was always at parties, usually big ones but also lower or single doses at chilled house parties a couple of times (easier comedown, but maybe just due to the dosage), but never alone at home. Mephedrone, on the other hand I have always taken at home, mostly alone in my room. I wouldn't be particularly comfortable in telling my friends that I have taken an unknown potencially addictive and possibly dangerous new drug (or much less offering them). None of my closer friends are much into drugs anymore, never been or try not to. I've been away from the rave parties and E for over a year, mostly because the people I go out with seem to have gotten over them. I didn't mind much since I had some accumulated some bad representations of rave parties in my mind, but now I mostly miss them. I still also want to try E at home though, prefferably with a girl. And, of course, going out on meph! I just don't feel like it's very appropriate to take mephedrone and be sweaty, clenching my jaw and jittery or shaking in a mainstream club, people usually are just drinking a lot, maybe when I go to alternative electronic music one. or when I go to another of those house parties (maybe in one of those I'd be more comfortable about telling someone about meph, the people that go are much more drug-minded , smoke a lot of weed and many have probably taken hundreds of pills over the last several years. The second time I got E was from an acquantance of one of them, in exchange for some of my mushrooms. =)
Ok, I wrote a lot here, so instead of remembering the other points I haf in mind when I started my message I'll rather just stop. Maybe this message would even fit better on a thread of its own, in the ecstasy discussion forum.
I'm getting a little tired of spending so much of my meph high on this (maybe that information was obvious already), but it's not very easy to stop adding stuff between the lines when so much "important" things come to mind, I almost started adding even further details of my experiences on fenproporex, which would be way off-topic. So, sorry about eventual mistakes due to my inattentive writing and hasty editing.
