i guess it varies from person to person, but theres no question that sometimes oxy makes me nauseas (sp?). puking is pretty rare for me, but once in awhile i do get nauseas. ive noticed it usually happens when i was up late the last night doing it, got a bad sleep, then i feel awful the next morning. and its not from withdrawal, its the direct effect of oxy. it is an awful, awful feeling, and im not sure why i get it sometimes and other times don't, but it sucks.
