Some tiredness is normal, but be careful. Have your Ammonia levels checked! It should be between 40-100 parts. With liver issues, parasite
waste, and dead parasites, it can get dangerously high like mine 240! I'm on 2 Meds to bring it down. Lactulose, (a laxative) & Xrifaxan. (an antibiotic).
It can affect your brain, & be fatal, if you start to black out, (lose time) instead of falling asleep, eventually you could slip into a coma, then there's no coming back from that!
