All day I have had nausea, dizziness, headache, and an ache behind my eyes if that makes any sense. I've been drinking water so I don't think I'm dehydrated. I also ate 3 x already today and even some snacks in between. Went to the gym and felt good while I was there but when I left I got sick immediately on the way home. I haven't vomited or fainted but my tummy feels iffy. I've also been having frequent bowel movements. Has anyone felt this way? Temp is normal. I just feel completely terrible. I can't read or focus on anything because my eyes get tired and start aching.
