Get it! I needed it on one cruise over Christmas break.
I was working with kids at the time as an Early Childhood teacher, and they're known for getting everything that comes down the gutter....including sinus infections, which I am chronically prone to.
About a month before the cruise, I started to feel like I had a sinus infection. I went to the doctor and told them about my suspicion, but I was told I had a Sinus Irritation and was prescribed a strong dose of Allegra. I would told that I would be better within 3-5 days. I was, but not for long.
The following week, I went on my cruise. 5 days into a 10 day cruise, I am laying in bed, too weak to get up, and dehydrated. When I finally mustered up the strength to go to the Infirmary, my original suspicion was confirmed with one 5 min. checkup: I had a Sinus Infection! I was immediately prescribed amoxicillin, and was told that I would be better within a week, but I would start to feel better within 3 days. They were right!
Thankfully, we had Traveler's Insurance, or we would have been up the creek without a paddle!
