I'm suffering the same thing right now so I totally sympathize. If I cough I retch, if I brush my teeth I retch, if I blow my nose I retch, if I smell something bad I retch. Sometimes I just start retching for no reason. Whew fun stuff! At least it's better than vomitting. Vomitting makes me feel like I'm going to pass out after, and if i have a full bladder it's not a good combination.
