I don't think there's a non-prescription version of flagyl, but I know when I was taking it a few years ago they were prescribing Pepto-Bismol in conjunction with it. Have you tried the Pepto?
Yes. Pepto does help, but is it good to take it every day?
I'm no doctor, but I doubt it would kill you to take Pepto every day for awhile. There is a reason the flagyl worked, and maybe you just never fully eradicated some bug that it was helping you get rid of (-?). Did they tell you what the flagyl was for? Maybe you should try it one more time, only don't stop the Pepto when the flagyl is done. But that's something to discuss with your doc. Good luck.
