Fergie, I had glandular fever and it does affect your liver (no chocolate or alcohol) and most people threat like it isn't dangerous but the liver (and the thing which stores blood) is swollen and if you do sport it might pop (so no sports for 6 months). You feel dead tired and awfull. I was up within the week but i haven't been 100% since i had it. It just keeps sitting in your body. (Most professional sporters don't come back at full potential after it). As said before most people threat it as a minor disease but it is actually quite dangerous if not followed seriously. I had a girlfriend who had it and she fell back into it after about 2-3 months (happenned 3-4 times). Just take it easy for some months reaaaaaaal easy no sports, a lot of sleep or it will hit you again and again. Btw kissing other people: I tried to give it to the current at that time but she never got it. But if your immune system is down/weak (like after an Ibiza-trip) you will catch it. See rest and no alcohol and chocolate.
