I had glandular fever when I was in my last yr at school. It's now 6 years later and I still suffer from the side effects. Constantly tired, get every cold going (always starts in my throat glands) and even at times, depression. All I can say, is just don't over do it! It will take it out of you for a good couple of days after (I managed uni and nights out, but alwasy paid for it after!!)... It's a rubbish illness, so rest as much as possible!!
Get well soon! xx
