Pricey, but extremely effective

My husband swears by this product. He has gotten no relief from no name products of this sort. Yes, it is expensive, but my husband will not take anything else. If pricing isn't a big deal for you, Definitely invest in this product and you'll find relief.

Dries you up within 20:00 minutes and keeps you dry for awhile. Tried others and so far this works the best with all the congestion in your nose and throat.

Packaging very difficult to get into. The smaller 50's are a tad easier to get by into but still difficult. But I do love the product just not the way they are packaged
