Wish I would have started using earlier
I wish I would have used this when I first felt bad...not a week later. I won't wait next time. I am using it now with Bronchitis and it is definitely helping.

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.

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.
