My mom sold for one of those MLM weight loss companies back when you could get the good shit with ephedrine.
I was working 6 hours a day plus high school full time, and trying to have a social life on the weekends. My mom gave me one of the things of their weight loss stuff with the ephedrine, thinking it would be healthier than caffiene.
First of all, hell no its not.
But I'd take that shit to LAN parties with my buddies on the weekend and we'd use it to stay up till 5am playing Counter Strike.
