Richard,
Thank you for the Holiday Greeting.
Withdrawal is a serious issue, and not to be joked around with. Please make sure you have a PDA or at least a pocket organizer available to get you through. Also, try printing out some of your favorite web sites and taping them to the car or plane windows. I find this really eases the stress and in most cases keeps the jitters away for at least a week. Absolutely essential - keep all sharp objects away for the duration which can last as long as 3 months. As a last resort, consult your physician. S/He can prescribe you Valium or Flexerol.
Good Luck, Travel Safely and Merry Christmas!
