Thanks for all your help folks!

I did actually have quite a good nights kip last night. I think it was because of you guys! Feeling supported and knowing that there are other people out there with the same problems helps.
I do have a variety of meds that I can take but I hate taking them. Some of them are addictive and some of them have awful side-effects so I try to stay off them. Obviously if things get too bad I will have to take something. But I am really pleased that I slept last night. Thanks again!
