I'm used to doing about that amount, you cant stay on your feet raving for 8-12 hours on one dose + a redose. The side effects are a lot worse and eventually you just feel cracked out and speedy, but dosage guidelines for MDMA are based on 4-5 hour periods. Add on the fact MDMA is diminished returns.
You will never get where you want to be after the 4-5 hours is up, but it'll keep you on your feet. I cant ever suggest it, but it doesnt fuck everybody up. I'd never suggest doing it, but thats what I do at raves. I've been reducing the amount I do, but thats how I take MDMA. I binge for a while, doing it maybe once every 2-3 weeks, then dont do it again for months and months.
My 200mg dose kicks me in the bollocks and thats how I like it. I get very messy, but I dont take MDMA just to feel good, I like being a mess. I dont get many opportunites to be like that. I dont like taking 100mg and then having to do 2 more bombs just to be at a good level, and then never get where I want to be because you've set your ceiling with the 100mg dose straight away.
