Meclizineis sold as a motion sickness aid for travel. In our area it is available at most pharmacies. A trick I learned is that while they frequently sell store brand "blister pack's" on their shelves, they also sell bottles of 100 sold by "Rugby" that they keep behind the pharmacy counter that you have to ask for. I have found this to be true at four national pharmacy chains. The bottles of 100 are much cheaper than the blister packs. Furthermore, Amazon sells bottles of 1000 tabs at a very reasonable price. As was pointed out in the article that mentioned Meclizine, it is a powerful anti-nausea agent.
During the holiday season of 2012, I contracted a heck of a stomach flu that was also morphing afterward into an intestinal infection. Our local hospitals were swamped with this "Bug", such that you had to wait in your car for hours for your turn to see an ER doctor. I have a very high pain tolerance, but I was in utter agony with nausea so bad I found myself heading for the ER. I remembered that I had printed the SB article, and on it was an anti-nausea OTC compound.
