Oh boy, oh boy, oh boy ... this is MY topic!!!
Perimenopause hit in earnest the year I got divorced. No more menses and no more husband happened in the same year. I *thought* at one time that the horror of having one's husand move out might cause early menses, but now I know that I was genetically preprogrammed for early menopause. I DID also eat like a HORSE that year and gained 20 lbs. Although I lost it again previous to discovering my blood sugar dismays, I do totally believe it was that year from the dark side that pushed me over the edge. Yes, type 2 runs in my family and yes, I have that lovely type 2 build (no waistline even as a small child), but I am certain it was that year that brought me to where I am so quickly.
Good luck with the menopause. It wasn't a pretty picture.
