Hi Fruitbat, welcome to the forum.
Glad to hear Vagifem is working for you, but as to the dryness, have you tried using a vaginal moisturiser? The Yes products are best, and some people like Sylk. I can recommend the YesYesYes website for more information.
As to whether menopause ever ends, well no, not really, unless we can suddenly start producing our own oestrogen again! Some folk find symptoms lessen over time and some don't, and need to replace the missing hormones. However, if you have VA then that will only get worse if left untreated, and treatment is lifelong.
This forum is a great resource, so ask away about anything else. To create a new post, go to the front page and select the heading you want (eg, All Things Menopause), then at the bottom of that page you will find a tab that says Create New Post.
