My parents both have type 2, and I fast every Sunday night until Tuesday morning. I don't think this makes me at all miserable, although it is easier if I stay busy. I also work a two mile walk into this. I'm thinking about asking my physician for metformin. I don't need it now, but in cryonics circles it is recognized for life extension properties.
