Awhile ago cyberdoc advised me to try d worm first for my stomach pains, then to see my doc if they continued. I was utterly disgusted by the thought that i could have worms, but I gave it a try. I took the normal 3 day course of d-worm and although I still have very occasional, very mild pains, they are certainly greatly reduced to the point that they are not worth mentioning, and also, the degree of flatulence (it was bad) I had is down 99%. Thanks Anrich.
