I am a 49 y.o. male with CFS for 3 years. I have the usual symptoms: fatigue, brain fog, digestive problems etc. There are some ok days, but I am at about 40-50% of pre-CFS energy. However, when I catch a cold my energy goes up 20-30% and I almost feel normal with the exception that I have the cold symptoms. Does anyone else out there experience a similar situation. In other words, do you feel better when you get sick? Thanks for any input.
