Stopping is a significant problem - it requires sustained decceleration equal to the acceleration time. And another headache is that we'd need highly exotic shielding to protect from particles of dust etc in the interstellar medium . When you're travelling at a decent fraction of c, colliding with such stuff would be disastrous.
