Hi All, really grateful for any input here. 
 

I am a Polycythaemia sufferer age 56 and have been for a few years now. I am pretty active playing competitive tennis 2-3 times a week, looking after 2 kids 9 and 11  ( with wife) and running my own business - desk based. 
I find currently that most days that I am tired in a way that I have not had before or at least not in such a persisting way. It is like everything is a physical effort and after a weekend of childcare I can't do much more than work for the next 48hr and want to go to bed at 8. 
what sort of levels of tiredness do others feel / experience?
