Drink water — I keep reading nonsense of drinking 8+ glasses of water, sure if your 9 feet and 300lbs than maybe. Yes be hydrated but on liquids….that idea that you need to drink a huge amount of water are based on studies from the 60’s I believe. Drink moderately, I say 1L is plenty if you drink other liquids. Water is best but staying hydrated makes the stool softer.
