Hi Sulfate,
Yes, I have been extremely tired at times, exhausted and feeling pretty terrible some days. Then "out of the blue" I could be almost ok again for some days (or hours), and all this in random order for about a year now. Never had anything like this before (now nearly 49 and in late peri, periods many months apart if at all by now). I keep exercising as I enjoy this but had to cut back due to peri, and also being in full time work still. I have had days when I really did not want to talk to anyone, low mood etc. I can now slowly see a slight improvement, so it must at some point get better (if 2019 is worse then it is HRT time for me). If you have not had a blood test it may be worth checking for thyroid, vitamin D and iron levels in particular. It is counter intuitive but sometimes a brisk walk or even a run can improve things and I feel less tired afterwards. All the best, Anna
