DEAR DR. ROACH: I have a suggestion for the lady who complained of heart palpitations without any apparent underlying causes. My late uncle, when staying in our house, always requested a big glass of water by his bed in case heart palpitations awoke him. He said that drinking water stopped palpitations each time.
It also works for me and others who follow my advice. It could be a placebo effect; being convinced one can stop the palpitation by drinking water gives one a sense of control. - J.G.
