Question about long sessions

[ramjet]

Being as its new years eve, I'm up for a phat party today, and I just wondered if I took a pill in say one or two hours time (2:00-3:00pm in Britain) whether, taking pills on and off (I have 8) from that point until say 4:00am (party finishes at 6:00am: Mylo, Groove Armarda and Plump DJs playing a set ;-)), I would be able to keep going, whether the come down would be unbearable, whether there are big dangers with stacking like this and whether I would loose the nice high by the time I got to the club? How long can you keep going for realistically? Can you stay relatively on the level if you space them out sufficiently or will long sessions like this simply mess you up?

Cheers
