Felt fine until about 2 hours ago, in fact I've been starving. I came home from work & prepared a salad to eat later. Then I went to watch a bit of TV when suddenly I felt very n*. Decided to go & lie down in bed where I continued to feel sick & a bit shaky & just odd really. I was overcome with tiredness & fell asleep for a hour or so. When I woke I still felt sick but was also sweaty (the hair behind my neck was soaking). I ate a packet of belvita cereal biscuits & now Im getting hot flushes on & off. Im afraid Im gonna v* cos I just dont know whats going on with me. My period is due in a couple of days but this is not how I usually feel. Any ideas??
