I know I'm supposed to wait for side effects, but I have been reading this site for research. I have struggled with endo. for aprox. 15 yrs. I've tried surgery, pregnancy, the pill, and as much IBprofin that my stomach can handle. My Dr. wants to start me on Lupron next week. Now I'm scared to death. I need to be a happy mom for my kids, not wacked out, unable to sleep or remember my conversations with them. Is this drug worth it. Should I just live with the pain? It sounds like this drug is worse than endo.
