I'm on Everol 75 & Provera 5mg (daily). The hair shedding thing for me has been long term, I have an underactive thyroid so have been on thyroxine for about 15+yrs, still have hair falling out. OH used to have to hoover my pillow daily!!
I can't say I've noticed it get any worse probaby if anything bit better sine HRT. My sleep is def better but was still not great a few hours a night, despite Magnesium & Vit D, change in diet etc. Very frustrating!! Sorry to hear about your vulval issues, sorry I can't help, have you read Maryjane's book? x
