I am beginning to think this will never end, as I have friends who have had a few months of discomfort / symptoms and then they are all clear, I am at nearly 12 years and each year feels worse. Sorry for the long story, but is anyone the same or similar?
I'm 63, in my 20th year since onset of perimenopause at 44, still distressingly symptomatic, most problematically with persistent vasomotor symptoms & debilitating insomnia. Despite working my way through the catalogue of HRT options over the past 11 years, I still get a variable no of long-lasting episodes (up to an hour) of intense overheating every night & the dreadful associated fight or flight cascade that can make it v difficult & too often impossible, to get back to sleep.
I do also get flushes by day but these are less problematic than those overnight. I can't sweat under any conditions & while this means I don't have to cope with the horrible effects of that as sadly you & others who've posted here do, it does make it very difficult to cool down, hence the overheating episodes & frightful adrenalin effects remain intense & last a long time.
I remember my Mum, never on HRT, still flushing into her late 60s & possibly until she died at 74. So like you, I very much fear I'll be one of the few who continue with vasomotor symptoms for life. I do have other systemic conditions complicating matters, meaning HRT's efficacy is probably compromised, so please don't take my circs as likely to mean you'll also continue to suffer given appropriate advice & help. I'm just posting in solidarity as it can be be isolating & v demoralising to feel an outlier with something that badly & persistently compromises QOL. Worse still, there can be a sense of personal failure when inevitably we compare ourselves with those of our peers who seem to have struck luckier in the menopause lottery.
Though I understand your clinician's sensible approach in starting you on a low dose given your age, I agree with the others that a 25mcg patch seems unlikely to control the degree of sweating you experience, so it seems well worth pursuing a dose increase & if this either isn't forthcoming or effective enough, another appt with a menopause specialist.
