I am entering perimenopause, missing some periods but not yet gone without any for a year. I did not gain weight because I was on a diet at the moment it started, so in fact now I look better than when in my 20's. My only symptom so far is hot flashes at night, but that is not uncomfortable, just funny.
Just a piece of advice: if you are having a premature menopause, ask your doctor to check your bones and your heart, which will stop being protected by hormones. Some (he) doctors don't pay attention to that and then women suffer the consequences... Good luck, and take it easy! It is not the end of the world at all!
