Can you please tell me if you drink a lot more than usuall and sweating at night has anything to do with menopause thank you very much i am 43 years old.

Yes, this is quite normal. Your oestrogen levels are falling, which is why you missed a couple of periods. The low oestrogen also causes the symptoms you describe. It isn't yet low enough to stop your periods altogether, but that will come. You could try taking a sage extract to stop the flushes, because they are quite debilitating and stop you sleeping, which causes problems of its own.
