... on mexiletine suck. My stomach feels terrible and I get pain which has been caused by the mexiletene giving me GERD. Does anyone have any suggestions to alleviate any of this. They put me on Nexium and hopefully I will get some relief from that at some point, but I am open to non-drug suggestions. Drinking a little fizzy diet soda seems to help some but not always. They said if the amiodorone didn't get to me that probably the mexiletine would. They were right!! Thanks
