Hi Rita & all When Jim started on Mirapex, his neuro told him to stay away from MSG. Did not elaborate, but it is hard to do. We do not eat Chinese food because of the MSG. but do eat soup, potato chips, tuna, and a lot of things that you have to read on the label to see if it has it in it. Did not know what the side effects would be, but glad to hear from you & your experience. Hope you are feeling better now.
