Late this afternoon I felt very faint, preceded by nausea, headache and the tremors. This occurred around 2:30 pm. I had not eaten anything other than coffee and a roll/bread for breakfast. The previous day I had a late lunch early dinner consisting of a bowl of soup and cobb salad. I felt my blood sugar dropped so I had a bite of salad and a couple of sips of coca cola. An hour later i vomitted everything in my system then fell asleep for an hour. When I awoke, I felt 100% better, had an appetite and ate prime rib sandwich and salad for dinner. Could this be due to the simple fact I was mal nourished for the day?
