Please try not to worry you haven't even tried it yet !

alot of people are fine with it !
Unfortunately you only hear of the bad experience not the thousands who are fine ,most dont post about about good things in most areas. We are not all the same and chances are you will be fine with it. Hrt takes time to settle 3 months is the normal time to allow it to work Im like you want it sorted yesterday ! However it dont work like that.
Yes you can get a separate prog.but give what you have a chance if you fret about it you will make it worse ,easier said than done I know. But think of all the women on hrt not on this forum because they are fine with it. I too sometimes forget we are on here because we are struggling but we are the minority not the majority I suspect. Hope you get settled soon .
