When I first looked up psyllium husk powder as a fiber supplement, people were complaining that it made the water thick and gross. That enticed me to buy it. And when the packaging said to drink immediately after mixing lest it thicken, I instead let it sit for a good 15 minutes until my glass of water had a smoothie-like consistency. Makes me love drinking water again and also sad that I can't have it with every glass of water or else I get stopped up.
