This is my go to cold medicine. I've been using it since I was young and it has never let me down.
Unlike other cold medicines, I don't experience drowsiness. I hate the feeling of being groggy that some other cold medicines produce. They just aren't worth it to me. I prefer to have a cold medicine that does its job without creating other weird symptoms.
Another reason to like this product is the format of the medicine. A ton of cold medicines come in pill format. I'm not a super huge fan of pills, and these little tablets don't require swallowing. Instead, you pop the tablets into water and watch them dissolve. They get fizzy and flavor the water. Its important to wait until all the fizz goes away so you don't end up drinking any bits at the bottom. I'm sensitive to liquid medicines which taste really chemically or mediciney, but this stuff tastes pretty good. You can drink it without too much cringing. And the best part is, you know once you get it down, your cold symptoms will start to improve.
This product works well and costs less than other cold medicine. For the number of doses you get in a box of this stuff, you get way less with other more costly medicines. This stuff is reliable and will hurt your wallet less than other potential cold solutions.
