They all work for swaying because they dry you up. If you want me to check a specific name I'm happy to do that but they're all drying. The only thing to watch out for is the kind of meds that inexplicably have both expectorant and antihistamine together since they're basiclaly the opposite of each other - expectorant makes mucus thinner, antihistamine dries it. It is actually silly they are sold together in one pill like they are, even for a cold remedy!!
