Speed is a fucking stupid suggestion.
Sure whilst you're on it you wont eat. You wont sleep.
And when it wears off you'll feel like shit and you'll feel hungry. Which will only make matters worse.
Do it the proper way or dont do it at all.
I hear ya. I just really like speed; not eating and sleeping are a positive side effect for me. When I come down I'm not really hungry, I'm just depressed.
As much as I would like to eat better and exercise more, I don't have the self control. I don't have the self control to have self control. I smoke and drink too much, eat things that I know are bad for me, and in the end I never feel any better. Well, that's a lie, I feel great until it's over.
OP, I was in pretty much the same situation as you. Nothing's changed except I've learned to talk to people (girls too). Doesn't make me like anyone any better, they're still all a bunch of goddamed assholes whose purpose in life is make mine more difficult. I have met some alright people as well.
There's nothing to it, but to do it.
