Hi, so I'm still being sick about once a week which is so much better but I've noticed I get hungrier more often now. Is this normal? I had lunch at 1 today and then by 4, I started getting very lightheaded and felt weak. Couldn't think why as I've been drinking water. OH thought it's probably because I need food so I've just eaten now and feel much better. I feel constantly hungry even after having a filling meal, within half an hour I start feeling hungry but I definitely don't give in because I don't want to eat more than I should be.
