I'm 49 and haven't had a period since August, so I'm thinking this is something to do with menopause. It happens several times a day and during the night, often interrupting my sleep. I can't really find the words to describe it, except that it's almost like a sense of deep dread washing over me and it's really uncomfortable and disturbing. Does anybody else get this, and is there anything I can take to stop it? I get a feeling it's to do with a drop in hormones as it's only been happening for the last couple of months.
