Hi, I have been extremely fatigued and often feel hungover even though I haven t had anything to drink but water. Also, I have gotten sick and my lips and face have felt like they were burning and tingling after eating the following: chicken gyro, Tom and Chee grilled cheese with tomatoes and pesto, fried chicken, and a donut. I m trying to figure out what this could be. Maybe it s a food allergy? I went to bed at 7 a.m. last night and made myself wake up for work at 7:30 p.m. today and still felt exhausted.
