Hi Devonroy.
I have been on HT (Zoladex) for three years with the inevitable side effects. My PC is incurable, and I will be on HT for life. When the night sweats became bad, I was offered Medroxyprogesterone, but I declined as I did not wish to add more hormones to those that were already causing me problems.
Later I was offered acupuncture to help alleviate these side effects. I had 14 sessions. It was an interesting experience, but it did not work for me. It clearly does for some people.
More recently I was offered Medroxyprogesterone again and this time I accepted. It's not a life-changer, but it has helped a lot. I now have far fewer hot flushes, and they are nowhere near as intense. The only downside is that the daily Medroxy took about three months before I felt any real relief. After the first three months, I continued to improve. I now get maybe three or four mild hot flushes in 24 hours. Any side effects are minimal in my experience.
I hope this helps. Good luck with your ongoing treatment.
