Fastest way to relieve cold/flu symptoms

If you have a cold or flu, this is the only medicine you need. Except maybe Tylenol a bit more Tylenol. This is the fastest way to get the quickest relief from any cold or flu symptoms. The fast acting comes from the fizzing getting right into your system. Try it. You'll thank me later.

The Best Available Cure all for Most Ailments.

This is my go-to product for most aches, pains, colds, sniffles, sore throats etc. Over many, many years of usage, it has been the most consistently effective of over the counter medicines for the everyday problems that don't rise to needing medical attention but do require something to still the problems. I'm specific here about the upper strength one for colds and flu for, I feel, it has some antihistamine that dries noses and coats throats. No matter where I go I have a packet slipped in my billfold 'just in case' which, often has been of assistance to a friend, fellow traveler or another suddenly found suffered. As with everything, some, few, may not tolerate it and, of course, it's not wise to give to the young without a release from a medical person. I buy it, endorse it, use it, believe in it, feel the maker is reliable....try it when you need it to find out for yourself.

I inhaled!

As soon as a sore throat or sniffles start I plop the disks in water and while they're dissolving I inhale the fizz deeply through my mouth then my nose many times, then drink it of course. Over the years this has always worked to either stop the cold before really forming or shorten the duration to 2-3 days. This last time the 3 adults in my home all got the same cold, but different varying times: 10 days, 7 days, 3 days. Guess who hit the Alka-Seltzer? Just wish there was a generic that was less expensive.
