A while back I took some 4-mmc (aka mephedrone, similar to MDMA) while wearing nappies. Wrote a trip report about it, copied below. TL;DR version - it's a lot of fun
The following is based on my pretty clear memories, and logs of last nights chat sessions, so the timings may not be spot on. Nevertheless, here it goes shulgin style.
0:00 200mg 4mcc bombed. Bodyweight 150kg, so this isn't a huge dose. Haven't eaten anything for 5 hours.
0:10 Start feeling something, seems unlikely this is actually a drug effect, so much as anticipation at taking a new substance
0:30 Definite effect now, tingling extremities and light headedness. I put on some eurodance, but don't really enjoy it at all
0:40 Come up very fast and very hard. It's really overwhelming and TBH not entirely enjoyable. I lie down, in silence and feel paranoid I might have overdone it
0:50 Much more enjoyable now - getting the sexual, empathic feeling I associate with MDMA. I change into a onesie and nappy, hide under my duvet with mny teddies and watch some Dora the Explorer. This is a lot of fun, I'm usually really repressed about my AB side, and can't really get into the whole roleplay thing, but now this isn't the case at all. I answer all the silly questions, and sing along.
1:20 I go back to my computer with the intention of putting on some more kids TV, but I'm now feeling too energetic to lie around. I cue up some happy hardcore on foobar. I can't keep still at all now, and have to tap my feet. The MDMA like empathic effects are already starting to fade, and being taken over by straight up euphoria.
1:40 I load up Sonic 2 on a megadrive emulator, to give me something to do with my abundant energy. This is a slightly annoying process, but when I'd usually get pissed off at, for instance, .zip inside .rar, now whenever I feel a negative feeling raising its head, it's crushed by a wave of serotonin.
2:00 Having been defeated by the fourth level of a game I completed 15 years ago, I head back to IRC. I hand out some what.cd invites at random to people I don't know at all. I spot a fellow AB I haven't talked to for about 8 years idling ICQ. We chat for a few hours about what we've been up to, drug experiences, work, and technology. Teeth grinding is quite severe from now onwards, which I off course deal with with a bottle. This also helps with the fact I seem to need a lot of fluids despite doiing nothing more than typing, in a 18C room.
3:00 I post thge following on IRC; I've finally worked uot the purpose of flip 3d in vista - it's so much better than the taskbar once you're of your tits
4:30 Euphoria has mostly faded, but the stimulant effect hasn't. I spend the next 3 hours continuing to annoy my neighbours with Bonkers compilations until my housemate gets home.
8:00 Go to sleep - a stupid idea, and I'm probably not asleep for 2 hours (3am)
14:00 Get woken by my too keen housemate. Can't get back to sleep at all, so decide to get started on my chores for the weekend. I fell like I'm slightly hungover, perhaps 5 pints worth, but this is likely down to the entirely insufficent sleep. Going outside to put up my laundry makes it apparent I'm not at baseline, as the cold air feels like cotton wool and colour and sound are unusually vivid.
19:00 (now) Still feeling some sort of effect - dry mouth, tingling fingers, compulsion to listen to music. This matches with my last MDMA experience, where it seemed to affect me for an unusually long time. Haven't eaten anything for 24 hours now either.
