@ca426 Sorry, Charlie. HE is hepatic encephalopathy which is somewhat common with liver problems, or at least it is with cirrhosis. It's confusion and irrationality that is caused by the liver not filtering out toxins, specifically ammonia, so it travels to your brain and causes HE. When one of these episodes put me in the hospital the neurologist suggested that my ammonia be tested, and sure enough, it was very high.
Some people with cirrhosis are in a perpetual fog, but my HE episodes were distinct and generally brief. Two to three days is overall brief, they last for weeks or even longer with some people. Most of mine lasted from a few hours to a day and required nothing more than my going to bed to sleep it off. Frankly, I have no idea why that helped, but it did. Perhaps since I was not eating, I was not producing ammonia and it just cleared out of my system.
