Before I began taking medicine for MG, my nose would run (somewhat) when I eat, especially with any type of grain etc. Now, since I am on 90 mg of Pry? geneic for Mestinon, my nose runs so bad, I have to go out of the room, blow my nose forever it seems. It runs to the point where I sometimes have to hold a napkin to my nose before I can leave the table. I don't like to go out and eat in public anymore. Having lunch with my coworkers has become embarrasing. Does anyone else have this problem since beginning the medicine. If so, what did you do. This is only when I eat and it seems to be with anything I eat.
