bigironkiller.... this will answer a couple of your questions. yes you can still work out on oxy. my g/f did that for a couple years. in fact you should work out on it simply because of how much the oxycodone will decimate your appetite if you don't. you may not be as strong, but you will get cut pretty quick, and get that "on top of the world" feeling. at least my g/f did - she lost 3% body fat in about 4 months. of course that now puts her at 8% body fat, which isn't really healthy. oxy is also really really addictive. do not tell your friends that you have it - one bad mention that their friend "person x" has it, and you can get robbed quicker than sin. oxycodone is found in percocet (which is cut with asprin, so beware of that) while oxycontin is pure opiate. anyways, hope that helps with the little bit i got...
oh, i should say she was on 200mg per day (5x40's) and ended up on 600mg per day (15x40's). addiction can be really bad with these. and when you're heavily addicted or it "kicks in" its hard to get your appetite back. above everything else, even the gym, do not get addicted to them. if you feel you are, ask your doctor to switch you over to dilaudid or fentynol - while still powerful, it switches you over to a different version of opiate that your body is not used to, which keeps your tolerance low. the more of a tolerance you have (in my opinion) the less appetite i think you will find that you have.
