Psyllium can't sit for more than a minute in the water or it is like drinking sludge. Swallowed fairly soon means it's more like an flavorless undermixed protein smoothie. Chlorophyll ( or two tbsp) really helps the taste, makes it minty. Taking Psyllium and Chlorophyll separately rather than together at first helps determine if there's intolerance to either. Also starting the Psyllium in small doses, starting with 1/2 to 1 teaspoon to tolerate the fiber change.
BuddhaBar, I came across this thread while searching online for celiac insomnia (having also scared myself stupid by finding out about fatal insomnia) and it did bring me some piece of mind as it so closely matches my own experience. I know this thread is old now, I hope you're doing well, and thanks for posting your experience.
That's great news, @HelloFlowersGoodbyeFlour. And you might find that if you do have asthma, keeping your reflux under control may help, if my experience is anything to go by.
