Hello Garnet, I use estradiol daily and ovestin twice daily but if I had a flare up I'd use it 3 times a day. I also apply a smear of coconut oil after each time I pee just to keep everything moisturised.
I've been doing this regime for over 8 months, I think, now, and for the first time in years I'm not 'aware' of all my lady bits, if you get what I mean. So everything feels normal. I'd definitely up your dose of everything down there.
