Great post Taz
I agree with most of what the others have said - there cannot be a definite answer because as Taz and others say the degree to which symptoms return if/when you stop HRT will depend on you as an individual and there is no black and white answer.
What is absolute though - is you will not have another peri-menopause if/when you stop HRT. What happens is that most women start to take HRT while they are peri-menopausal, and the ovaries continue to do their thing in the background, becoming less and less efficient. Eventually they pack up and ovulation no longer occurs. In the two years immediately following the last period ( ie the menopause) - hormones continue to fluctuate a little - but nowhere near the level at ovulation, and gradually decline to their final much lower level approx two years after the last period. There is some low level activity for some years after this though.
If you have been taking HRT all this time - when you stop you will have well passed the time when your hormones are going haywire, surging up and down, ovaries are pumping out eggs or not. All will have ceased, and all is stable. You will no longer have that to contend with. What happens when you stop HRT at this point is that your oestrogen levels just fall steadily with all the changes that occur - eg bone turnover ( increased), bladder problems etc until it gets to the low level it would have got to if you hadn't taken HRT. No more mood swings - but possibly permanent low mood/anxiety - depending on your individual make-up.
That's a very long-winded way of saying the same thing that Taz said - but I'm not good at being brief!!!!
If you want an explanation - simple one here about what happens in peri-menopause:
http://www.menopausematters.co.uk/article-perils-of-the-perimenopause.php Lots of other information on the main site about menppause, and a technical one here about the stages of reproductive ageing which summarises what happens at each stage in terms of hormones (FSH and others).

Kdee69 was not asking for help with who to go to or a private specialist - she was just asking about menopause! She is already on HRT and did not indicate she was unhappy with it! Do you work for him or something as you mention him in almost every post?!!!
Your questions are not at all stupid kdee69 - it is a natural thing to ask. I knew absolutely nothing about menopause and HRT except for periods stopping and flushes starting - when I started skipping periods!
