Just a general observation Steven but of my three family members who had chemo tiredness was a definite.
You have to remember that although your chemo may have finished 7 months ago, your body still has to repair itself. Chemo is a drastic treatment, aimed at destroying cells. It will destroy some good as well as bad and your body is playing catch up.
Just because you are back at work (long days they seem to me) and look OK doesn't mean you automatically have to be. You are also exercising which is also stressing your body.
Give yourself and your body time to recuperate.
I'm sure those who have gone your route will be along to advise you
