@pps26 I am so very sorry about your current situation. I could not imagine care taking of a human who is very sick. I can barely keep up with the needs of my old greyhound. I am almost 80 and am on 500mg of Hu five days per week. As I have said on here countless times, it is difficult to determine what-is-causing-what at this age. I am tired but also old. So I listen to my body. I get up in the morning 7-8ish, do some work, and by 1pm, am ready for a nap, which i take every day, then I get up and go again, till bedtime 11ish. Tired is the only side effect I can pin on Hu, and perhaps, Id be tired any way.
