I have been feeling off colour for a few days now and today feel very lightheaded, very, VERY dizzy and sort of disconnected (iykwim) i dont feel ill as such, just a bit sicky, tired and not at all right. I have eaten plenty today (even if I hadn't, I am used to going days without eating) I have been tested many, many times for anaemia and i am all clear. any ideas o'wise mners?
