I love this stuff. It works so well. I always keep a tube of it around me and whenever I think I'm going to be in a situation where I'll be around people that are sick, I just take one of these tablets. There is a weird taste to it, it's kind of like an orange seltzer taste, but after you get used to it, it'll be fine. My trick is to get the smallest amount of water possible to dissolve the tablet in and then quickly just swallow it.
