Menopause at 33 is very possible. My SIL had hers done and dusted by 35. The bell curve goes from mid 30s to mid 50s. Being on either tail end of the bell curve does not make a person abnormal, just a statistical outlier.
That said, internet diagnoses of something like this are useless at best. As Eye-of-Round mentioned, it could be a symptom of something serious and testing for the onset of menopause is very simple. You need a doctor not a bunch of internet peeps with too much time on their hands (yes, I include myself in that).
My personal experience of going Primal is that it fixed my problem of being too cold at night. I no longer need to wear socks to bed. Have you considered that perhaps the same heavy blankets and sleepwear you used last winter are no longer needed?
