I'm in my mid-40's and have noticed some changes but I'm not sure if I'm losing it!
My periods are still regular but the PMT seems to be getting worse. I retain so much fluid I actually ache in the days before, I'm completely wiped out and my co-ordination disappears.
My skin seems to be prone to allergies, had to throw some gorgeous face cream away as it made my face swell and dry up! My skin overall seems drier-having been the owner of greasy skin always, I'm now having to throw moisture at my face or I feel like a dried up prune 
I'm not sure if this is middle age or something if I'm heading towards hot-flushes? Not adverse to HRT but when do you start? Is it now (if I am peri) or when menopause is in full swing?
