I currently have a legit script for it and only use it very sparingly, a dose or two about 2-3 days out of the week. I could NOT get addicted to it simply because I HATE the sides I get from it with everyday use. Heck I still hate using it just once in a while, because every time I do use it I get bad anxiety from it, just start worrying for no reason, I can't stand that feeling! And if I use it consistently my short-term memory goes from awesome to absolute crap, that might be the worst side for me above all. I'd have to double or triple check stuff and I'd still forget things. No doubt it works awesome for killing appetite and for pre contest I could see it being a very good tool, but the thing was when I used it everyday for a couple months and then decided to completely stop, my appetite went insane and ended up going from leanest I've ever been to back to low/mid 10's in bodyfat %.
Now Vicodin I could somewhat see myself get addicted to. Makes me very social like amphetamines(if not more so) but without any of the anxiety and memory sides, also gives the same kind of motivation that amps do. It's the most perfect social anxiety/motivational drug I've ever taken, it's probably a good thing I can't get it easily or have a script for it. Just wish I could have that all without the drugs, I've had those SA and motivational problems ever since I was a very young child. Wish I could permanently fix the brain chemistry problem or greatly improve dopamine and/or serotonin problems with some natural supplements.
