Maybe not, but it's the ****. I've had a mucussy gaggy thing going on the last year or so. Whenever I ate anything with the least bit of fat or grease in it, or stuff like gu or shot blocks when running or biking, I would have to fight not to hurl. Literally, the only way to keep from hurling was to hack up every bit of mucus in my throat, and spit it out. Not ideal for burgers with clients. I tried musinex, no improvement but at least it made my throat bleed. I got a prescription for aciphex, after 2 days, I was completely cured. 2 months later, still cured. Fantastic stuff.
