I'm always feeling nauseous, dizzy and feeling like i'm going to throw up. Two months ago when all this started, I went to my doc and they did a stool sample and said I 'probably' had a bug but everything was normal, no fever or high blood pressure. It continued to happen for weeks but I had other symptoms so my doc scheduled a mri for my head but it was normal. I wake up feeling so sick and I have diarrhea when I wake up but an hour or two after I wake up i'm fine. I'm male and I eat regularly, I usually eat an hour after I wake up because if I eat right when I wake up, it makes things worse and I feel sicker..
