I've usually had good luck with plain old Altoids (peppermint, not sugar free).They seem to have enough peppermint oil in them and I don't have to wait for it to get through to the part of the GI tract where it dissolves, so I think that is better if you need immediate relief and don't always need it all the time (if you need it all the time then enteric taken regularly may work).The Altoids have the advantage of being really cheap and easy to find. Most grocery, convenience, etc. stores have them here with the gum and mints section of the candy aisle.
