“ Give yourself plenty of time. It can take many months before post-stroke fatigue starts to lift. The more you push yourself the worse you are likely to feel. Accepting that it takes time to improve can help you to cope better.”

Also, I think a few months is a good and hopeful goal. The article also notes the variation.

“ There have been a number of research studies on fatigue after stroke. In one study, two years after their stroke 10 per cent of stroke survivors said they were always tired and 30 per cent said they were sometimes tired. In another study, at least 12 months after their stroke, 50 per cent of stroke survivors said tiredness was their main problem. You are most likely to experience fatigue shortly after your stroke.”
