If you can get me safely to .999 C, slow me down, and get me back to Earth at .999 C, sure. The entire trip for me would only be about two years, provided a consistent 1 G of acceleration. Just please make it so that reversing acceleration doesn’t completely screw me, so my spaceship doesn’t have to do a complicated flip a bit after the halfway point on each trip. I’m certain that wouldn’t be good for my stomach.
