No, I haven't thought about sleep apnea nor been tested. The doctor didn't even bring it up when I saw her on Thursday. I'd be most unhappy to have to wear a mask at night, especially since I'm a side sleeper....I don't sleep well on my back at all, never have. We'll see what comes up. I'm going to try using potassium and magnesium together instead of just one or the other.
Will keep you posted.
