I hate to say it, but speed drugs do work for weight loss. Not for everybody, of course, and it's a fucking unhealthy way to lose weight, and when you stop you've got to deal with withdrawals AND the weight may come back, BUT it does make you lose weight. Problem is, I've got so tolerant of speed that I can take Adderal and eat just fine on it. IF IT WERE ME, and I had access to and motivation to do this, I would obtain crystal meth and do bumps prior to each meal. It would limit my intake and make me less hungry and I might do bumps in between meals to avoid feeling hungry. Of course, this brings with it all the health problems that meth invariably brings...teeth grinding, insomnia, paranoia, anxiety, high BP, etc.
