I´ve got a question for anybody here who has POTS (postural tachicardya sindrome) or knows about it. I use sports drinks like gatorade or powerade to ease my symptoms, which I read works by increasing blood volume. Do you think that I should take one liter at once like I do, or should I take smaller sips over a longer period of time? This I ask because when I take those drinks, I seem to loose most of that water trough urination, which increases notably. Thanks!
