Flying Tips from the Cyber Celt

Here are some suggestions about our fight to Hungary from a blogging friend of mine who commented on my personal blog. I just wanted to post if as "food for thought". Anyone else have anything to consider?

Cut salt from your diet for a day or so before you fly. Drink lots of water, no coffee or soda. When flying, wear nonrestrictive clothing and shoes you may easily take on and off. Walk about the cabin when you can, find ways to put your feet up.
