In reply to Lawrence Dudley:
I had it in September, and it sucked. I think it varies a bit from case to case, and I didn't help myself by trying to ignore it as it started. I guess I was bedridden for about 3 weeks, then spent a month doing very little. I lost a lot of weight, so I ate massive amounts of carbs, sugar and fat for a month or so to put the fat back on, and that helped a lot.
After that most of the symptoms disappeared, but I would get tired out very abruptly when doing anything approaching exercise. I would feel fine for a mile or two, then within a hundred meters I'd get tired, nauseous and sweaty, and need to take a nap. The amount of activity I could do gradually increased until I could do a full hill day by about January. That's in keeping with what my doc said: 2 to 6 months to fully recover. At this point it was helpful to exercise regularly but stop
well before the fatigue started, and take a rest day if I did get to the fatigue stage.
Finally, it took several months to get back some of the muscle and fitness I'd lost being sedentary. Though I could have done that faster by training properly.
Amusingly the only other symptom that carried on a while, at least according to my gf, was snoring. It seems the swollen/dry/bleeding tonsils left some scarring or something. That tailed off in December or so. Not that it bothered me much!
