It appears that the ibs-d urgency, cramping, and loose stools benefit from ketotifen, and it is rather dose sensitive in that I likely need 2 mg twice a day, at least, which I think matches the studies published on the topic. Anyone have recommendations for an online dealer that they have previously personally utilized and that ships to the US or Canada (preferred), without needing a written prescription? I hope cyproh will work better than ketotifen.
