Thanks for your reply westy.

tashybabe - thanks for your reply too. Im not sure if its dehydration - i drink between 3 and 4 600ml bottles of water a day, plus a glass of milk, juices and cups of tea etc. I think (think!) im getting enough. I have had a few headaches the last few days?

I have decided that if I dont feel better after a sleep this arvo, i will get DH to take me to the ED and see what they have to say.

Thanks again.
