Hurdity, you are right that if receptor site 'burnout' were a serious issue, we'd likely know about it by now! There is a lot of seemingly valid info (i.e. practitioner reports seeing such-and-such with so many of they clients) that is really just anecdotal info, so I apologize for not investigating further before throwing that thought out there.
To answer your question, I am fortunate in that I've experienced very few meno symptoms and would like to see how my body does without any intervention. The bottom line is I'm not 100% comfortable with the idea of long-term use, so I'd rather try it without. I've dropped down to very low dose for about 6 months now, (HRT, as a whole, for just over 2 years) so will gradually taper and go off maybe in the fall. Will use local treatment as needed if VA becomes an issue.
Hoping for the best. Guess that's really all we can do as well as good self-care on all fronts.

You sound like you have a very well-rounded approach and I'm trying to do the same!
