This is a very recent addition to the forum's Health Pages, thanks to Jim (aka JmJm530), who collected and organized all this. It is very useful.
When I finished tx I felt the same as I did while on tx, by the end of a week I felt really bad and wondered if maybe I was going through some sort of withdrawal. I never did find out a clearcut answer, but, almost 2 months later, I feel much better. No muscle pain, joint pain, getting better, no nausea or headaches. For most people this all gradually resolves at varying rates. Do mention it to your doc though.
