Does anyone have experience using Zoladex ( goserelin) for chemical castration? How well and how fast does it work? What dosage have you used. Are the side effects worse than other drugs?

I only have about 3 days experience at this time as I was just given Zoladex by my Dr. From what I have read, it is very similar in action to Lupron. I haven't felt any different 'yet' but am hoping my T starts dropping soon. The implant injection was completely painless. Doc says is the 1 month formulation is good for me then next month he will start me on the longer acting formulation.
