Hello and welcome,
I agree with Flossie, ( always such a supportive forum member ) that it may be a good idea idea not to do everything all at once.
I kind of did a bit opposite to you, unaware exactly of my best options when peri hit, I decided to not have hrt but sertraline instead. And whilst this did indeed offer me support, other hormonal symptoms came along which the ADs could not help with. So in my case, I took myself off the sertraline, with my gps knowledge and commenced hrt.
It was not my best idea to do all this at once as my body got a bit overwhelmed with too much going on. So Flossies advice I believe is sensible, as you may find if you decide on the hrt regime, this may help enough without the additional AD. Of course you can always add this on after speaking with your g.p at a later point.
This forum covers so many subjects, not always hormonal.so do indeed post with any questions or have a little rant or ask for help. Everyone on here are so kind, informative and supportive.
