What were the side effects you felt?
You feel mildly ill all the time while on it (9-15 days is a normal cycle)
You sweat. MDMA makes you perspire lightly in comparison, your mattress will be destroyed after a few days, you will need to change clothes frequently during the day completely soaking them in sweat. If you sleep on a towel it will be soaked within minutes. You can't sleep at all, so you take ephedrine to stay somewhat awake.
Everything turns yellow. Your eyes, your piss goes electric green, your cum goes yellow.
You can eat what you want, carbs make the sweating more intense, but training is an ordeal and you will hardly be able to do it.
You hold water, don't feel thirsty yet you have to drink loads of water due to the sweating. Taking glycerol also helps.
In short, you feel like death, but after two weeks you look like you've been strict dieting for two months.
