That's actually normal. I take Subutex. I often feel like shit for 4-5 days, when I re-induct. (I still use occasionally).
I think the bad feeling is the sub replacing the opiates on the receptors.
Also, switching from a full-agonist opiate(heroin, etc) to a partial agonist (Suboxone,. Subutex), is uncomfortable. It will get better.
You're not in precipitated withdrawal. If you were able to type, and actually string thoughts together, you're not in pw.
Precipitated withdrawal causes some hysteria in most people. It's very intense.
The longer you can wait, the more effective subs will be. I've found if I can get to 40+ hours, the induction is much smoother. But, I know how difficult that is. Easier said than done. Hope you're feeling better.
