Hi! Many thanks to both of you for replying.
CLKD: i started the hrt journey due to poor sleep patterns and the night sweats/day sweats. Both resolved almost within a few weeks of starting hrt. The current fatigue issue comes and goes but doesn't impact greatly but I will try the Vit D, there's not much sunshine in Scotland at the moment!

Maybe the cramps are the latest phase of "settling down"??
DottyD68: wow, that's a long time! How do you cope with all the ups and downs, changing side effects and different medications? You must have great patience/tolerance! Wish I was like that. I have wondered if I should come off completely to see what happens as we've tried a different dosage. Have you tried or thought about this yourself? Maybe my body is not good at tolerating hrt?
