My potassium is huge problem when having an attack, They give me infusion after infusion and I keep losing it, have no idea why, they just keep the bags coming until my episode starts to calm down, really crazy. As a result my calcium, sodium and potassium is always low and I have to take supplements for them, even with supplements hard to stay in theraputic range? I suppose it is part of the syndrome? Hope info helps a little, sometimes no rhyme or reason? Hope and pray Connor is doing better.
