According to Rick Steves (Rick Steve's Europe on public TV) the best thing to do to fight jet lag is drink lots and lots of water and get some exercise. According to him "jet lag hates bright light and exercise." He was just on the other night giving travel tips and that's why I remember so distinctly what he said. So, put those kitties of yours in that little stroller and out for a walk with you - aches or no aches!
