Lupron and sleepness nights

Only on it for 1 month so far and already having issues. I apparently have the worst case of endometriosis all my doctors have seen, including a cancer specialist that had to do all my surgeries because of the severity. Granted, I am only 31 years old and have had a full hysterectomy. So, after 3 surgeries I am still having severe abdominal pain and bleeding (don't know where that is coming from since I don't have a uterus anymore) so they said try Lupron and I finally gave in. Now I started getting such severe pain in my lower back that I can't stand for longer than 15 minutes and terrible side aches. I started getting headaches (which I already take pills for for years now),and have gotten the hot flashes as well. What are we to do ladies? I am so sick of complaining to the doctors about pain. You feel as if you are a big cry baby. What are my options here and does this ever stop?
