As Dr. Berg points out on YouTube, a classic symptom of low potassium is hearing your blood/pulse whooshing or banging in your ears. I keep a pot of potassium citrate crystals by my bed & a quarter teaspoon in water gives me 300mg of elemental potassium, the amount in a small banana. As I don't want to be eating at night, I just pop some into half a glass of water along with half a teaspoon of magnesium citrate (magnesium helps the cells retain potassium, apparently), let it dissolve for a few minutes then drink it down. Stops the banging & calms me down within a few minutes. A level teaspoon of Cream of Tartar only seems to contain around 500mg of elemental potassium (the amount in a large banana), so shouldn't be an issue. A glass of coconut water contains a decent amount of potassium, so having some of that on hand is helpful too.

To Ann of La, Ca--Yes, a teaspoon of cream of tartar equals or contains 5 grams of cream of tartar, not potassium. A teaspoon of flour is also 5 grams of flour. No dangerous information was given. You misunderstood. It wasn't 5 grams of potassium. A teaspoon or 5 grams of cream of tartar contains 495 mg of potassium.
