Hi
You can buy a potassium-Mag suppliment...one pill....they are very resonably priced even in most drug stores and supermarkets....$3-$4 a bottle...I have to take a Water pill every once in awhile to help with the swelling in my feet...it flushes out all the minerals with it if I dont take a potassium supplemnt with it Horible leg cramps happen.....Big John
