I'm having a current love affair with Methylone and I do it extensively. I can't get enough of it. I started out rolling once a month... now I want to do it at least twice a week and it's getting expensive.
To me, I think it's perfect. It feels like MDMA, just not as harsh. The euphoria is great, but not overwhelming. You don't get too much on the stimulation side, but you won't care either. Oh, you won't be able to sleep though. I know that I usually can't sleep for a day after.
The crash isn't bad after you get used to it and in my experience it's gotten less and less each time. The first time I did it hit me pretty hard. Over a week of depression, being tired, memory problems and feeling "burnt". Now when I do it, I'm slightly out of it for about a day or so, but no more depression and then I'm back to normal. One thing I have noticed upon repeated use is that now when I crash I see hallucinations like light flashes or things moving in the corner of my eye. That's something that never happened before on the first couple of times. That takes a little while to go away, usually a few days to a week.
People say the peak doesn't last that long, but for me it lasts a good while especially when I boost it. I usually take 250mg to start, and then another 250mg in an hour. After that, I'm usually good all night.
My only complaint is that it seems I'm building quite a tolerance to it. I'm noticing that every time I take it, it still does its job, but nowhere near like it did the first couple of times. I've only been using it for a few months. I know I really need to take a break, as eventually it won't do anything. It's just so hard to resist right now.
If you want to try it, start small. Usually 250mg is a good dose for most people. Another thing with Methylone... the more you take the harder the crash, but not the better the peak. Over a certain amount Methylone just stops being effective and you just magnify the crash. For me I found that 500mg is good and sometimes I'll take 750mg if I can't stop myself from compulsively redosing, but I've taken a whole gram before and THAT is a nasty crash. So, the whole point with Methylone is to only take the smallest amount needed.
Typing this post is making me itch for it so bad... but I was blazed twice this week already.
