I've found that about 25-30 hours is about my maximum, too, and it works best for me to do the hours in a few long working days rather than across many short ones - so that can have entire days of rest and isolation. More hours is a double whammy - lost recovery time is as critical as the extra workload. Any more than that, even in work that's rewarding and in a comfortable environment, and the cumulative effect means that a burn-out is pretty much guaranteed eventually.
As I wear down, it makes my anxiety and depression progressively worse, and my autistic traits become far less manageable. I strip my private life to the bone, and use annual leave for recovery time rather than holidays etc., but it gets to a point where inattentiveness at work and the constant need for sick-leave understandably make me a liability to my employer. I've lost quite a few jobs that way - though I didn't know at the time that they were autistic burnouts, as I wasn't diagnosed yet.
This is without the added demands of CFS or Tourette's, so as Fnord said, it sounds like you're pushing yourself pretty hard already.
This is a point I keep making to careers advisers. The ability to work a full week occasionally doesn't mean that it's sustainable long term. Rest and isolation are the only remedy for burning out that I've ever found - little and often is far more productive for both employer and employee than poor work quality and sick-leave when things start falling apart.
You make a good point. People think just because you can do a week's work (full-time) - that you can do it long-term. Especially government bureaucrats who want to deny people even small amount of disability payments. I find I'm already using annual leave for rest more than any kind of enjoyment.
