Hi,
My original Zoladex treatment ended in August 2016, in the months that followed, I felt no improvement of the HT side effects. I still felt very tired all the time , no improvement in libido or anything.
I was so disappointed that I had a testosterone test in the following May and the results came back at 0.3 instead of being in the normal range of 7 - 31. In other words, it was like I was still on HT treatment. A couple of months after that, in the July, it was obvious that everything was back to normal. My libido was back and I felt like a teenager again.
So, that was nearly a year for things to return to normal for me, so maybe, don't expect things to happen for a while. Like with most treatments, everyone's bodies react in a different way.
I hope everything goes well for you.
Steve
