I've experienced full blown throwing up, to bad bone pain is what it felt like, never comfortable, head aches (more of a intense pain in my skull). That was off of taking around 100-250mg max of pure hydro. I've also had WD off of oxy, going from 150mg a day for about 3 weeks. So I've had WD I know how bad it is I don't want to feel that again espically off of sub's or any drug like that. The only reason to do suboxone is purely due to driness of pills that I have normal access too.
