Last Saturday I was really dehydrated after spending all day outside running, had eaten very little and that night I had 3-4 alcoholic drinks. At one point during the night I thought I was going to throw up, I did not and I stopped drinking at that point. During the last week I ve had an upset stomach on and off but no vomiting, no fever, little appetite, stool is slightly softer but not significantly so. The pain comes and goes, and varies in intensity, sometimes it s barely noticeable but then it woke me up last night. Any suggestions? (One friend suggested that the brat I had last Saturday night might have something to do with it)
