I started HT, then RT a few weeks later. I found the last weeks very hard, and was totally exhausted. Mind you, I was working full time, having to do the years accounts and being a parent of a 10 year old. I would often need to sit very still for an hour just to recharge, as energy levels were perpetually low and would get drained easily. I've not noticed any change on the emotional side, but my job is very emotion based anyway (therapist).
Five months on from the end of RT, energy levels are very much increased, but still not up to where they were before all this started. Probably around 80% at the moment. I guess that's still some recovery from RT, and the effects of Bicalutimide 150mg. I do subscribe to the idea of working through the fatigue by keeping active - despite the instant effect of exhaustion, I feel it increases endurance and stamina which can only be useful. And now, it's a sunny day and I'm off out rock climbing til dark!
