The dissolvable onandestron will actually work very well, probably better than something you have to swallow if you are already v* or close to it. The only question is can you stand the flavor, if you can or they're flavorless there is no downside. Onandestron does have a downside though, it can cause constipation and headaches. Worth the risk if you are actually sick or being treated for a chronic condition that causes nausea but a bad choice for "just in case," and kind of expensive for that to boot.
