Hello Denise R,
I have been suffering from extreme fatigue since perimenopause began, but now that I'm one year post-menopause (theoretically speaking this is still perimenopause) it's not as bad.
I think the disturbed sleep (caused by hot flushes and anxiety) is the main culprit. As long as you can control those to some extent you will be feeling a bit better. Another important factor is muscle fatigue. We tend to keep doing the same things as we used to do before menopause and we just don't have the same muscle flexibility and strength so we have to take it easy on house chores and high impact exercices, at least until you can adhere to a physical workout routine (which many of us don't). Meanwhile, hang in there and keep smiling, it truly helps.
