Constant illness?

Hmmm... It doesn't sound like Aids, but you should have the test done if you haven't already. Have you been checked for kidney or liver failure? What pills/Vitamins/Meds are you on? If you are taking anything you are not sure of, stop taking them. It really could be so many things... environmental, for example. Think back to when you first started becoming ill. Was there a drastic change in your life before things started happening?
