I was wondering how many people suffer from diarrhoea relating to their cfs. For many years I thought it could be dairy or wheat intolerance and I was also tested for celiac, but the truth is it flares up with the other autonomic symptoms such as the fast heart beat, vertigo or night sweats. In the past it was constant but now I can go for months without an attack, and then, if I overdo things, it will return with bloating and emergency toilet trips which are horrid. Does anyone else get this symptom if they overdo things? I have had an attack this week, which is expected as I have been doing too much, I had heart issues last weekend with sweating at night, so it has come as no surprise. Can anyone identify with this? I must add too that my muscles twitch more than usual when I get this.
