Thanks sydney moose for your reply! Definately craving carbs and am trying to stick with low GI. I felt a lot better yesterday & today - still alittle lightheaded but much better must have been a rough patch there. I am going to try to work this one out for myself for a week & if no change I'll see my GP I am just putting it down to being older and having a child to look after so resting is a lot harder. I did go to bed early last night & even though I woke earlier I think that helped alot.
