Drugs are not a contest!
I personally really ****ed up on E in the mid-90s and stopped taking anything but a big bag of skunk to clubs/parties for 7-8 years. I have recently got back into Es and Mushrooms but find that I can only take them once a month because I need atleast 4 days to recover properly.... I always think that if I have a really big one then the massive buzz you get just gets evened out by a shallower but longer fuzzy period.
Peace.
