You have my sympathy for the time change between Vancouver and Middle European Time. NTL, IMHO, being doped while flying (as a PAX) rather sets you back a bit if the shite and fan are about to meet. Mercifully it's been rare, but I've been on a couple "screamer" bad turbulence flights. If you're not strapped in tight and miss the warning bumps... Not Good. Again, ride your own ride.
