Its a battle to get VA under control and a lot of it is trial and error. My regime is Vagifem, Ovestin and a moisturiser, I have been on this treatment daily for two years, that's how long it can take and even though I have been trying to reduce the dosage I have failed and still need daily treatment.
Up to you how you want to treat your VA but all the treatment is out there if you want to give it a go, nothing to lose all to gain!
