Hi
Yes, my peri was gradual over 3 years. I started getting hot flushes, then a few cluster headaches as my periods become more and more irregular, various other symproms crept in and then Bam! Last September the sky fell in with horrible physical, mental and emotional symptoms that sent me to the edge. I tried various 'natural' remedies and approaches but nothing touched it. So I started the long winded process of getting HRT. Long winded because the GP wanted me to have a number of tests to eliminate anything else first and of course there is the wait between each test and then results and then another wait for the next test etc etc. I finally started HRT in January this year and the improvement was immediate and dramatic. 7 months later and I feel so well, it's like a miracle.
So I'm with Dotty. Get yourself to the docs. If you look at the Treatments tab on here it will take you through what's appropriate for your particular physical circumstances. If you are confused about what to ask the doc for, there are several very well informed women on here who will, I know, come along and advise you. Make sure you know what you want before you go the doc. Many of us have found GPs to be very poorly informed.
Let us know what you decide to do. There is hope, a lot of hope for a much better day than you are having today xxx
