Mabel, I think popping to the doctors might be wise, just to have a chat, there may be an underlying cause. When you don't sleep it can affect so many things in your life, and makes you feel so rough. The menopause may defintely be a contributing factor, as I too am going thru that, as you may have gathered from my posts!
I don't like to recommend you take tablets, but I have had trouble sleeping for years, and I take Nytol, the One a Night Nytol. I don't take it every night, but if I've had a few bad ones I then take one. Just to break the cycle. You can get them from most chemists, tho some only stock the herbal Nytol which I don't find work as well.

I hope you feel better soon, and get a good night tonight.

I'm keeping the florist busy today! Snowy xx
