endometriosis
"I was actually on Lupron Depot for 18 months.  My periods stopped within a week and my pain was gone within the first month.  I almost didn't go on it because of the horror stories I read online, but I'm glad I did.  My skin broke out more than normal, but nothing a little makeup couldn't hide.  The hot flashes were intense at first, but slowly started to subside.  After six months they completely stopped.  I also fully understand night sweats.  The side effects were well worth it to me since I no longer have cramps that hurt so bad I pass out.  I am also enjoying being period free after never having a regular cycle and being anemic the better part of my life."
