Hi Vashti,
I just wanted to welcome you to the forum, I only started hrt in august, so more experienced ladies will be along to give you some really good advice. This site is really fantastic and has helped me loads. However I just wanted to share my experience.
In february I developed tinnitus, I had really bad anxiety prior to that and panic attacks, I developed sleep issues, none of which I had previously. I realised that it was my hormones and when I had my blood oestradiol levels checked at the end of June they were <19 (very low) (i am post meno by about 3 or 4yrs).
I have been on estraderm patches mx 25 since 25th August, then increased to 37.5mcg in sept.
The hrt does seem to be helping my sleep and my anxiety. It does take time, it isn't an over night fix.
So other ladies can give you more tailored advice, do you still have your uterus? whereabouts are you in your menopause journey?
Sorry for such a lot of information, however from my experience I have found the estraderm patches to be great. This isn't to say I might not need to change them later on, as sometimes its like hitting a moving target, but for now, they do seem to be helping me xxx
