Hey brother (or sister). I feel your pain. I just got out of a treatment center today after spending 21 days with some of the most amazingly courageous and likeminded people I've ever met. Before I went in 21 days ago (21 days clean! Most in almost 6 years!), I was also on a Suboxone taper program, and it did not work out well at all. My best advice is to either tough it out, go into a program, or find some way to get Librium and Catapres. Just enough for like 4 days. These drugs helped IMMENSELY in getting me off the Subs/Oxy/heroin. Then I highly suggest you get into the NA fellowship. Honestly, I know it seems so stupid (I thought so 2 years ago when they preached it in the local rehab), but there's nothing more therapeutic than talking to someone who's in the same **** you are. Almost everything they talk about completely hits home with me, and I'm so angry with myself for not trying this out before.
I really hope this helps man (or woman).
