last evening, my boyfriend and I had eaten supper, of a pork chop, scalloped southwestern flavored potatoes, a glass of red wine. We went to bed about an hour later. I woke up about 1 1/2 hrs after going to bed....with violent diahreaha, nausea, cold body sweats, and a dull head ache. This lasted for about an hour. I am diabetic....but had not had a problem with anything as low or high blood sugars for a long time. What could this signal??
