Thank you so much everyone for your replies, it really does reassure you when you know you are not alone and other people have experienced the same things you are going through. The night sweats and sleepless nights are the worst, the dizziness was frightening but am now getting used to it, I will definitely try the food and drink little but often, maybe that is something I am remiss in, I look after my 2 year old granddaughter and never really think about having a drink and find that I can go through most of the day without drinking so maybe that is it, will give it a go anyway.
Thanks guys and keep up the good work, it is so nice to know there are people out there willing to share. x
