My symptoms began last Saturday. I watch my grandson and he had a slight stomach disorder during the same week (Tues thru Sat but with vomiting and diarrhea). I started out being tired with slight nausea but no vomiting or diarrhea. After a few days, the heartburn, feeling a little bloated and gassy. Yesterday and today, the heartburn is really uncomfortable. I just purchased some Prevacid today and started it. My symptoms include the acid reflux and a burning sensation below my breastbone with a slight headache. I feel really tired because the heartburn is keeping me from getting a good s night sleep.
