Laparatomy symptoms and conditions

ok, so I am 28yrs old just had my second lap for endo and my doctor has recommended lupron, after reading this I am soooooooooo scared to even get near this med. Its like you either take this with the hope of saving fertility and no pain..or not and have endo ravage your body and you will live with unbearable pain!!! I have no idea what to do, my post-op surgery appt is this week, and i am so scared after reading this. Is there anyone that did not have weight gain, headaches etc...anyone that can testify that lupron actually worked for them? Cause right now its my health on the line, my ability to have children, my ability to have a normal life free of endo pain or these crazy, horrible side effects...please help me!!!
