I have noticed a correlation between low energy and watery stools. One of the things I have found helpful with energy levels when I have watery stools is electrolytes. I load up on them. I have capsules with no sugar or anything that I take daily (regardless) and chewable tablets that I take as needed from a company called "Saltstick." These are meant to be taken throughout a sweaty workout, like every 30 minutes, so they're not that strong. Same thing happens when you have watery stools as when you sweat a lot: the body gets depleted of electrolytes. I feel an immediate effect when I take them, and when I have watery stools, I take them throughout the day.
I have noticed that powdered psyllium husk helps my stools be less watery. I take a pretty small amount, like a teaspoon with water before each meal. I have noticed greater gut integrity and have had no obstruction activity since I started taking it, whereas before I started, I was getting painful kinks every few months at the spot where I have an adhesion. I don't know how small the area is through which your stool has to pass, so this could be inadvisable, especially if you were to take a large amount of the powder and not enough water: there is a warning on the bottle not to take this for bowel obstruction. In general, I find the powder (mixed with plenty of water) to be extremely gentle, but I wouldn't take it or anything solid while in the midst of an obstruction.
