lupron

My urologist has me taking an injection of lupron every three months and I have now been getting them gor the last 2 years and he says I will receive them for the next year also.Has anyone else out there been on lupron this long. The side effects are getting extreme and I also have read that being on lupron for this long will have adverse affects by making me become un-responsive to this therapy after some time has passed. Any info would be greatly appreciated. ...
