Hi, I was diagnosed with this last year. Initially I was put on Vagifem, then later added Ovestin, plus every moisturiser you can think of! As it was still not enough, the GP suggested systemic Hrt which I gratefully took. Everything slowly improved till I didn't feel like I had a problem.
So I foolishly stopped systemic hrt whilst keeping up with the Vagifem, Ovestin and moisturisers. Two months later and I'm in VA hell so have had to go back on maximum dose of hrt, so 4 pumps of gel. I'm really hoping I can recover this time around.
Most women seem to do fine on the locally-based HRT, though.
