've done pill containing BZP b4, and def agree 1 time might have had a come down, 2nd time not at all other than expected tiredness from going crazy till 4:00am(then that was late lol). The first time, I crashed hard over the following 2days, but I also had sunstroke, and major sunburns and grass burns which I seemingly appropriately attributed that to. As for the roll which they all seem to refer to disparagingly, I had quite the time, although I def had other stuff in the pill as well such as L-Arginine, guarana and cayenne and ginger, etc. Also, maybe the form of processing it/purity?. At any rate, some say that meth is way better. I'd rather not touch it... I definitely noticed a difference than MDMA, however I'd say it was in some senses comparable, though perhaps, more needed.
I def had a longer high with the 2 pills I took, about 10 hours. I'm sure of the contents of the pill btw. It definitely didn't fade as I came out of school and went to Adult Ed class later in the day, and came home... Lol, interesting conversations with my teacher;p
I can say def hydrate, and eat before and during. And Tulsi tea

I would especially like to experiment with using 5HTP in conjunction.
