Hi sorry, I havent been on for ages. I couldnt be bothered getting used to the new forum and I've forgotten where I've posted previously.
I dont know if my answer is going to be helpful as I cant really remember how long I was off. I was off the time suggested by the medical team and went back part-time. It was fine but I would get home and fall asleep. I think I could have done a few less hours to begin with and built them up more gradually. I think I returned full-time after about 3-6mths and that is what was too much. It was manageable but it just felt too tiring. However I was on hormone treatment at the time as well and getting those side-effects.
