When you say you are constantly peeing, do you mean the urge never leaves you? Menopause can cause many symptoms, but a 24/7 urge to wee seems extreme. Have you been tested for UTI?
Also do you have an IUD at the moment? One of the things I was told when I was searching for answers was that I should get my IUD removed as this can cause bladder issues. In my case, I had my IUD removed and I still had urinary frequency/urge/. Have you had any urge/frequency issues prior to this?
There is no simple way for you to get help unless you present at a doctor in person and get examined. At the very least, you should get a referal to either a gynaecologist or a urologist. There are specialists who do both in Australia, but I don't know if that is the same in the UK. At a minimum they should do urine tests and an ultrasound. I hope you get some relief. When I was at my worst (pre diagnosis) I used to take a drug called doxylamine at night. It's called Restavit here and you can get it over the counter. 25mg at night used to get me a complete nights sleep and did not leave me drowsy the next day. It is actually an antihistamine, but it is used as a sleep aid. I haven't had to take it for a long time now, but I still remember what that constant urge felt like and how exhausting it is.
