Perimenopause and Femoston

Hi,
I have looked through the active threads, and can’t see anything recent about Femoston, (apologies if there is a thread).
I’ve been perimenopausal for at least a couple of years, I would guess. Periods go missing quite a lot now, so I assume I’m deep in/heading out.
My last period arrived after 2 missed. OMG! The pain, the distress, the PMS was unbearable this time, although the bleed wasn’t too heavy. The moods and the awful behaviour was the deciding factor to speak to my GP.
I am snappy, aggressive, intolerant, emotional, quite a lot, (confirmed by family, friends and colleagues). This leads to shame and embarrassment, which is soul destroying. It hasn’t helped that I’m literally a few weeks into a new relationship, (after separating amicably from a husband of 24 years, 2 years ago), and I’ve already apologised for being weird, flaky and emotional 3 times. He’s a decent guy though, and so far, is patient.
I haven’t been sleeping well, have occasional temperature issues, but nothing too significant. Dry skin, dry eyes, weight gain, and joint pain. So pretty standard for perimenopause, I guess.
My GP was fabulous. We discussed and agreed HRT: Femoston. I collected the prescription and started yesterday.
I’ve had a night’s sleep and have spent the day, dozing on and off. I already feel calmer - I forgot to mention the constant anxiety and anger I’ve had.
My question is: is this a quick response to the Estrogen? Or just that I’m feeling better as I’m getting some control over this ridiculous journey?
How soon do you feel the benefits of HRT?
I’m considered low risk for this medication, as am 49, with no family history of breast cancer. I had a mammogram quite recently too, and breast tissue is healthy.
I’d love to hear about the experiences people have had with this or other HRT’s.
Thank you all ❤️
