to do things? I have heard people whine that they only have 250 t-cells and can't do anything because they are fatigued yet they have no o.i.'s.

I have HIV w/a cd4 of 108 and have run several marathons and work. Yes, I do get tired and have had various minor o.i.'s

Isn't the preception of the number and being tired without any type of o.i. just pshchological?
