This is funny, cause I too always keep bananas around for potassium. As I'm always low as well. Prednisone can sap it too. I also take a supplement for potassium. Potassium sups. are also good for cramping that Mestinon can cause .
One other thing about food, and MG. Eat as natural as you can. It's not easy, I know, but if you can get organic foods, those are probably the best for us. I know I can't always do it, but if you can, it really is the best way to go.
Check labels, and chose the one with the least about of chemicals. And it's very important to take Vit. D. B12, etc..And always let your Neuro know what kind of vitamins you're taking, cause things like Echenasia(sp?) are bad for us. My neuro always wants to know the brand, the amount..etc.. It's all very important to our health. Annie may know more about the vitamins.
