I'm only able to eat like once a day because I feel uncomfortably full after eating regular portions. I ate at 2 today and feel so full, almost like I could vomit. I have a headache too because I think I'm dehydrated but drinking water makes me feel worse. I exercise daily so I know it's not due to inactivity. This started about a week ago and I've lost about a pound. I didn't ever have morning sickness- is that what this is? I hate the feeling of fullness, it's torture
