This is what I always use when I feel a cold or the flu coming on. Whether it really works, or simply hides the symptoms of the flu is yet to be determined. I do feel better when I take this stuff, but it may be that it makes you forget about your symptoms by putting you in a daze. Because I definitely feel "spaced out" when I take TylenolFlu, and I have trouble concentrating. And if you combine this stuff with ibuprofen, you can get a good buzz going on & then you'll completely forget that you're sick. Of course you'll pretty much forget about everything else for several hours too...like how to drive a car, where you live, what your name is, etc. Small price to pay to feel better, I suppose...hehe.
