Hi Anna67
Perhaps you could tell us where you are in menopause - such as what your cycles have been doing over the past year or so (how regular and whether you've skipped many periods) and how old you are? Or perhaps you don't know because you've has a hysterectomy which is why you've been give oestrogen only? That is one of the old-fashioned types of HRT but does seem to work fine for many women. Also you've been started on the highest dose initially - which sometimes can cause side effects.
As for being "me" again - well what most of us hope for is to eliminate the worst of the menopausal symptoms for most of the time - but we do still expect not to feel 100% some of the time just as with our periods or in pregnancy! Often the physical symptoms go quite quickly ( on the right HRT at the right dose) but the psychological symptoms can take longer and especially if you are still peri-menopausal and your hormones are fluctuating.
It's a good time also to look at your diet, weight, exercise and lifestyle and to make any changes necessary to improve your health as you move into this next stage of life!
Do tell us a bit more about yourself and also do ask anything else - women on here have experienced most things between us!).
