I was diagnosed with IBS last year and I have been managing it pretty well, if I get really anxious that will upset my stomach but otherwise food has been okay. Something different has happened recently though since I have turned 21, I have been enjoying drinks at dinner with friends. I normally do not drink a lot because that usually makes me very sick, and I generally just like to enjoy a drink or two with dinner versus going out partying (which makes me anxious). Although now, even after 2 drinks with dinner and drinking plenty water, I will be violently sick the next day. The number one thing I notice is that I am super congested right when I wake up and then I begin to vomit mucus and water for most of the day until I sleep it off and eat later. I do not know if the sinus congestion and the drinking are just compiling on one another, but this has happened with the mucus the last three times. I also get diarrhea, which makes me believe it could be my IBS.I expected that I had not drank enough water the first two times,but this weekend I drank plenty of water. That is why I am wondering if even just alcohol is affecting me worse now . I do know I am not going to drink again because it was highly unpleasant and debilitating for over 24 hours, but I am just confused on how such little alcohol with water and dinner could make me so sick when it has not before until these last few times.
