My son had Epstein barr when he was 17 years old. We had a hard times - he was so tired and he seemed to catch evey virus and cold that was going around; we seemed to be getting nowhere with it. Finally, I put my foot down with him, I made him get more rest, I changed his eating habits - he ate healthy foods and he took a theragram vitamin with extra everything in it. He slowly did a turnaround. It took time, but it did work for him. Hope this helps.
