i AM also on Campral and after being on it for 33 days I drank, but when I was drinking I would take some of my doses but not all, like once I started drinking i wouldnt take that dose , so a couple of times I drank and I felt weird later on and a couple of times I had only drank about 5 beers, maybe 6 and so talk to your doctor and it may have something to do with the Campral, another thing is my doc told me to stay on the meddication even if I drank, but then to call and talk to her if I had any type of symptoms.
