I don't have CFS. My chronic fatigue is different, because I don't have PEM. Because I wasn't able to understand PEM I often recommended exercise to my friends in PR. Now I understand that exercise just worsens them. I started this thread to explain more about my condition and eventually ask if there are others like me here. The thing is that I'm able to exercise - I can still cycle hard for an hour. Now that I'm used to not being understood by healthy people, that I'm sick, sometimes even pr members ask me "So, when exactly are you exhausted?" , or "Is your condition just psychological then?". I'm exhausted all the time. I feel like I have drunk a bottle of vodka the previous day and have an awful hangover - that includes awful fatigue, heavy head with headaches, brainfog and palpitations. Or, I feel like I've caught a cold - the symptoms are the same as hangover, aren't they (excluding the sore throat)? Now I don't know about you, but in the years when I was healthy, even that I sometimes caught a cold or drank and had an awful hangover the next day, I was still going out to cycle. While not in best shape and not being able to compete with others, it was still some kind of training, which didn't make me feel worse. I'm doing the same now when I'm sick with chronic disease. My condition is as psychological as cold or hangover are psychological. They aren't psychological! I'm just able to make effort without consequences after that.
