thanks all!
orange plum - i don't know that i am doing anything special, i drink about 3 lts of water a day and at the moment, take minimal exercise as i tend to get light headed (maybe low blood pressure, am going to drs next wk).
i have started a new job though, and am finding it very anxiety inducing, my mum reckons i am burning nervous energy through adrenaline!
dawnie, keep at it, my lovely - it works!
