There’s no specific point in time when you should reduce your working hours, but the tiredness you describe could be a reason to try, for example, working 75 per cent of full-time hours instead of 100 per cent. You may need a slightly longer recovery period than is possible whilst working full-time. It’s worth noting that fatigue could be a side effect of dopamine agonists or low blood pressure, or alternatively another condition such as anaemia, etc. But of course, it may also be part of the illness itself. /Dag Nyholm
