Hi, I'm currently taking LYRICA for my ibs pain and it works well with the exceptions of the weight gain and the Cost . With the ridiculously high cost of the LYRICA along with the costs of my other meds , I'm easily thrown into the Doughnut Hole, which I'm sure most knows what that means as well as how costly it can be for you depending on how many other meds your taking and how many more months until the end of the year. With that said, my question is, as I've just learned a little about it within the hour, how well can TOPAMAX replace the LYRICA for ibs / nerve related pain ? Thanks
