Jetlag

Suffering worst jetlag ever on second day after returning from Europe. I never experienced such a bad jetlag for past 5 years when studying in the States. I am sleeping at the wrong time...Sleep in the afternoon after lunch time, and then sleep again after dinner time till 23.00, and I couldn't sleep after that. Other than jetlag, I should begin to create a checklist for preparation to relocate to Hannover. At the same time, going hunting for tour package to East Asia.
