I read about this somewhere else and I think he described it well especially since most people don't mention that the type of experience you have could also be different. I also think that a persons background on use is important as I think it greatly influences the way you experiences it so I included it here.
The guy said that he did it two consecutive nights in a row, and said that they were two completely different experiences. It was his 4th time using ex, 1st time was in 2002, second time was in 2010, 3rd 2012. So his experiences where very spread apart. I think this was important because his brain had a large amount of time to rest in-between. Anyways, he said he was going to a weekend long event and had only planned on rolling on Saturday of the main event, It was from Friday till Sunday.
He tried to load up on antioxidants to help with the nuerotoxicity and the comedown. 5-htp was only taken on Monday. After the rolls. He also tried to take it easy on the drinking on Friday and Saturday before the roll and was completely sober at the time of Rolling both times and he took mollies.
Dropped at 11:30pm took two doses of Aprox 100mg(200mg in total) and dropped another at about 1:00am (100mg aprox) As he wasn't sure the exact amount that where in the pills.
This is how he described the Saturday Roll:
It took about 45 minutes for him to feel the effects. He just felt generally really happy, was happy to meet anyone and everyone, he loved to give out hugs because he wanted to share the joy he felt with others and like the connection he felt to them when he was hugging them. (His teeth were def grinding, as the stupid security took away every all all packs of gum.) Was really energetic and danced his heart out. The roll also come on much slower but lasted a much longer time. He could also feel the pulses of the roll which went from a peak to a lesser peak in a pulse, felt good and had a great time and didn't start feeling tired till about 6:30 am. Went home tried to sleep~and dozed on and off for about three and half hours, He couldn't sleep to well because had to keep going to the bathroom every half hour
Next day when he got up at ten felt a little lethargic, loaded up on Antioxidants, and headed out to the first event of the day a pool party at 12. By the time he got there he was feeling a lot more energetic and just generally pretty good.(However he didn't feel like drinking till about 2 when he started to feel like he was fully having a good time.) Had 3 drinks at the pool party then went to the next event at 4 where he followed it up with 3 more beers and at about 6:30 stopped drinking because he just didn't feel like it and at about 7:50 all of a sudden all the energy just left him, at which time he went out to go eat with friends and then went back to the hotel to take a nap for 1:20 minutes. His mood he said at this time was feeling okay, but a little tired. <-because he was feeling tired was part of the reason he decided to drop again.
Sunday night experience was completely different. Took same dosage as Saturday night, except waited till 1:30 to drop another one.
Took it at 11:35 and it hit him super fast and super hard.
When it first came on his head felt all hot and then it felt like his head was quivering for about 15 minutes. The ups and downs of the roll where really intense as in the fact he would really feel it and then it felt like it completely subsided. His mood was very different, this time he said that he felt like he NEEDED to hug someone, The hugs still felt good, but they where just very different. His teeth never grinded but his jaw would quiver along with his muscles sometimes. This time he felt really intrigued by lights and just gave him a really pleasant weird feeling(never had that feeling before whenever he rolled). For some reason he got a lot of joy typing out text messages on his cellphone because he just like the way the screen glowed and stuff. The experience was def over a lot faster and the second drop didn't have as much impact like it did on saturday in fact by 2:30 am he didn't have the much of the fun feeling effects and just felt very introspective and didn't really feel like doing anything but just dancing on the dance floor by himself listening to the music(he felt good and enjoyed it), but sometimes he felt annoyed that people would try to come up and dance with him. by 4:30am he started to feel tired and over the next hour really started to wind down. Till he got back the hotel at six, where he felt really peaceful and took a shower and hoped into bed and dosed off till 10:40am.(This time no crazy bathroom breaks as he tried to make sure to drink less water.) Which he woke up and felt okay just a little tired at which point he took more antioxidants, then went to the drug store to buy some 5-htp and B-6.
The reason he said he shared all this is because he found the answers to be really incomplete. As he had thought about rolling the two nights and tried to look up what people thought about it and it's effect. Most people just said it was a waste of time and not worth it. Others where like you can do it. No one really took the time to kind of explain why. In his opinion it was still fun to do it the second night, however it was not the really thrilling fun experience that it was doing it the first night. He also thinks that he would of spaced out drops way differently, maybe spread them all out so that the feelings the second night would have lasted longer and spread out more of the evening because he really does feel like it wore off really quickly. (but he said he's not an expert when it comes to things like that and hasn't really read to see what other people recommend so he would check out what they say.)
So here's how he broke it down.
-Something you could try, but he feels like he will never do it again as it just wasn't that great especially since there is a possibility of more damage to the brain.
-It just wasn't as fun as the first night.
-after thinking about it he realized he was taking a dose equivalent to 3.5mg/kg of body weight.
-He was expecting the second to be exactly like the first but less intense and a little shorter from what he read but wasn't expecting it to be completely different.
-Side note he also said he was shocked to see how many people rolled all three days
I hope this gives you a little more insight into it
