@primek thanks Kath for sharing with me I think I'm starting to get the hang of how this cancer business works, i think you have confirmed what I suspected that going back to work FT may take its toll and Its likely my exercise will suffer and fatigue may well increase, so back to square one, I've got used to working 4 days which means I've been able to increase my exercise on the three days off. This morning got on the scales and have finally lost some weight which has made me feel really happy so I'm keen to hang on to my exercise regime. I guess I need to bite the bullet and see what happens. Luckily I've been using accumulated sick leave but that won't last forever. My plan is to return to work 9 day fortnight for a few months as a way of pacing myself. Like many of us I've lived a flat out busy life and pacing takes a bit of getting used to. Thanks Kath for all your contributions on this site I always find your information and many other people's story /information really informative Lyn
