It`s no where near as bad as oxy or heroin. I went thru a detox using subs in 11 days. This was to end my 5 year addiction to heroin and any other opiate I could find. I started off with 2 the first day and worked my way down to a half of one(4mgs) on the last day. This was how the Doc wanted me to do it. I felt super the first 2 days then on the 3rd I started to feel like crap. The sub had started to leave my system. I had WD`s for sure but they were in no way as bad as morphine,H,oxy,tabs,whatever. If I had to go through that again I would have tried to ween down a bit more,at least to 2mgs before stopping.
