I took them, by the directions.. then ignored the directions because it was like speed. More was better.. and so I took more and more. Sure I got super skinny, but I was really destroying my body and my mind.. always wired, taking handfuls of pills and then drinking a ton afterwards to 'come down'. That didn't end up well either
I hope she's safe and maybe if she talked to her doctor she could find something that actually works better, safer.. I know there's a bunch of newer and safer things out there now for people to try.
