I had Glandular Fever in February, although it wasn't diagnosed until three months later. After the initial illness ( which I didn't realise I had at the time, just thought it was a fluey thing ) I felt wiped out, run down and had recurring symptoms for a good four months afterwards. Rest, healthy diet and tonnes of vitimin supplements, and I've felt pretty normal for a couple of months now, but if I overdo it, I feel crap again ( fatigue, flu like symptoms, depression, insomnia ), so I am taking it easy, and slow down when I feel I need to. I have been exercising though, just listening to my body. The post-viral side of it can go on for a very long time, and I've read some people never get rid of it, and it becomes chronic fatigue. Evil GF!
