I might add, since I take a cousin of the medicine, Lyrica, and also had IBS a few years ago (from a different drug I was taking), that those Gaba medicines can dry out a person a little, which then might goof up digestion sometimes, and also the mouth will dry out sometimes. A very simple thing to do, to offset that particular side effect, is to drink several extra glasses of water every day. You can go to some drug websites to read all the side effects, I think drugs.com and rxlist.
