I too had a hormone shot prior to receiving 40 radiation treatments and following a rise in my PSA 5 years after my prostate was removed. The shot was the 6 Month Shot. Some 14 months later I was still getting over the impact. I did not do well with the shot - many many hot flashes daily + night sweats, loss of sleep, depression, emotional outbursts (crying for no reason) and a 35 pound weight gain.
I had a high Gleason score of 9 at my time of diagnosis and learned that surgery after radiation was very problematic so I decided to do surgery first. IF you have an interest go to www.TheProstateCancberCoach.com where I did a series of videos on my 8 weeks of radiation and my reactions to the 6 month Lupron shot. How long your reactions will last is unknown - best advice is to keep active with exercise - I found it helped a lot - I also picked up a small hand held fan with a water spray it helped a lot in the summer months - ditto on a ceiling fan when i slept. All you can do at this point is work your way through it. There are some drugs you can take to help offset the impacts of Lupron etc but I understand they have issues as well. Good luck and keep us posted
