hi Graham, I'm a little ahead of you, so maybe I can encourage you a bit, although everyone is different.
Identifying when I stopped taking bicalutamide needs a bit of assumption, because the last treatment was a 3 month injection, and the 3 months ran out about 6 weeks ago, of course the drug didn't disappear overnight.
The first 3 of these 6 is very difficult to separate out because it was masked by the side effects of the radiotherapy, the fatigue was far far worse!!
But after the 6 weeks since the bicalutamide ran out , in theory, the fatigue and hot sweats are already a rare visitor, perhaps once a week. I can now safely say that the other side effects, muscle weakness and energy (somewhat different to fatigue) are improving rapidly. Afternoon naps have been replaced by dog walking.
One final side effect which hasn't yet improved significantly is the stiffness and locking of my finger joints, although I've been able to continue playing my ukulele. I'm sure that in a couple or 3 months, that will resolve.
So to pull it all together, my radiotherapy and bicalutamide finished about 4 to 6 weeks ago, and I feel pretty good..
I've joined Slimming World to try to get rid of my embarrassing gut, I'll report on this is due course (if successful)
Good luck, a positive attitude is your greatest ally!!!
