I've 18 months now of on and off. Three months of periods then 3 months off with hot flushes and night sweats.
My last period was in February and I thought that was was it, but lo and behold the hot flushes have cooled off and I now have all the symptoms of PMS.
To be perfectly honest I prefer the menopause symptoms to the horrid bloating and aching joints that I get when pre menstrual. I have actually felt better without periods in spite of the thermonuclear heat I give off.
