Hello, Beginning early this morning, at about 3am I was experiencing pretty bad nausea, which felt like it might escalate to vomiting. I proceeded to take about 5 doses of Pepto-Bismol over the next 4 hours during which time the nausea would subside and return in earnest. I proceeded to go to work as usual and felt better with only two more occurences of sudden, startling nausea, once at about 10am but it vanished soon enough that I didn t take anything for it. Then again around 4pm along with a migraine type headache. I was hungry by then in addition to being slightly queasy so I ate, took my regular prescription medicines and migraine Excedrin, and had a lie-down and felt better after about an hour. I went to bed at about 8pm and haven t been able to sleep and the strange feeling of having something stuck in my stomach began to grown and then pain in upper left quadrant so now I m a bit concerned. I did have some awful fish for supper last night and perhaps that is it but I just don t know.
