according to the consultant I saw last week:
low mood, tiredness and irritability is nothing to do with hormones or peri menopause or HRT (despite the fact I was prescribed low dose citilopram for PMDS)
Utrogestan doesn't cause issues (i am likely progesterone intolerant and couldn't take the pill in earlier years). And the suggestion is that I take it daily now (my periods/bleeds are absolutely regular and haven't changed).
Increase in weight, digestion issues and acid reflux must be my diet, not peri (diet hasn't changed, except that i am having to restrict more foods not to feel unwell)
Buuut if I do stop HRT now "all my symptoms will be worse".
So options are live with it, increase SSRI and acknowledge "not everything is menopause related".
I guess I just have to live with feeling rubbish. I don't even feel very cross about this, just resigned.
