Zoladex

Anybody else with endo ever tried the zoladex implant? It's used in men with prostate cancer to slow the growth, but it's been proven to help slow endo growth and pain. If you have tried it, was it a positive or negative outcome? I didn't get any changes from when I had it. It was over the course of 6 months and the needle was huge. >.< went through that pain from a thick needle and a clumsy doctor for nothing it seems.
