The counterpoint to this is these are people who have dedicated their lives to becoming astronauts. They want to go to space and they want to do things in space, and they have sacrificed a lot of the comforts of a normal life to reach that goal. I suspect most astronauts feel like they don't spend enough time in space. These are people who are driven by a passion to do the thing that they're (involuntarily) having to do more of than originally planned. I don't know if "how would you feel" is a good yardstick here; I would probably get sick of it pretty quick, but I'm not the kind of person who would make a good astronaut.
