I've been dabbling with very part time work. I find some weeks it works out well in that the experience is mainly very uplifting and it's helped restore my confidence. However on the days when deep down I know I should rest more, it's a real bind and even barrier to my continued recovery.

I'd say if you can negotiate a truly flexible set up, so that there are no repercusions in the short term at least, if you call in sick last minute, then go ahead. The problem is with not working until you're symptom free is, if it's a long time away, that you feel down for not working.

This is a very hard decision and everyone has unique circumstances. Trust your instincts and allow yourself to change your mind if you need to.
