I'm on my third monthly zoladex injection so far, and I'm always a wimp and have the injection to kill the pain first (for some reason my brain has gone completely blank on what this is called!).
It's been really good thus far, and the difference in how much I've changed since starting has been amazing. The drop off in testosterone is really noticable though and it can really leave you lacking in energy and feeling a bit low (you're supposed to adjust to that after a bit, I just haven't quite got there yet!).
