I wonder about something for the anemia? That makes a person feel tired and sluggish; if that is addressed, it may help him feel better.
I said in one of my posts while just rambling on... I have anemia myself so I know how it makes you feel. It got so bad last November that I had to go to the hospital and get 3 pints of blood. I was so tired that I was having a really hard time walking from one room to another! I felt almost 100% better after I got the blood! I now take 325 mg of Iron each day. But Iron supplements can to mess up your digestive system at times. But that is something we can check into later on.

I am going to go to that website you posted and do some reading. Thanks for posting it!
