Good Luck North. I was on Erleada and ADT in a clinical trial for 13 months ( surgery too). The meds certainly made me tired and I slept poorly. 2 years ago my doctor gave me 2-4 years but I have been off of meds for 10 months and my PSA has remained at .01 and testosterone rising in 10 months to 125. I have recently switched to a vegan diet and I hope that this might help. Feeling really good now. I think that I might be doing better than expected and I will visit with my surgeon in a month and inquire if he might up my prognosis. Good luck to us all!
