I've been feeling uncharacteristically ill today, and I was wondering if anyone could take a guess at what might be the cause of offer a suggestion. I woke up with headache, nausea, and some general dysphoria and sound sensitivity. I felt like I had a severe hangover despite no recent alcohol consumption (certainly none the day before.) I got myself moving and to work, and either my symptoms subsided or I didn't notice them as much since I was busy. After work I made plans to meet with some friends, but my symptoms began to return. I told them I wasn't feeling well and returned home early. I have since had a resurgence of nausea with vomiting, headache, and oddly some attention difficulties. These symptoms are acute (began this morning) and unusual. I am still feeling crummy and am awake much later than usual for me, so I guess I can add insomnia to the list. I am not sure what could have precipitated these symptoms except possibly some recent elevated stress and perhaps not getting enough sleep. Any thoughts are appreciated. I sincerely hope that I can just "sleep it off" and wake up better tomorrow.
