Balanced commitment to work

I am currently recovering from that sickness bug, and mixed in with it, I had a touch of flew I think as well. And before any women start it wasn't man flew. I was sick over the weekend, and am trying to get back to work today, things to plan for , and things to ensure our supporters know what is going on. Still very hot and shivery though, so where does the balance between realising our sickness and our commitment come in. I have felt a need to get back to work, but don't know how effective I am going o be Id there any point in being at work if not effective? How do others work this balance?
