I think travelling West to East seems to intensify your jet lag for some reason, perhaps because is more disruptive, or runs counter to the body's circadian rhythm. Either way having just travelled for 36 hours non-stop from Norway to Sydney on Friday I'm just completely exhausted mentally and physically. Was great fun, and we really didn't want to come back this time. You really get the feeling that London in the summer is really one of the worlds best cities, so much going on, and I loved seeing new spins on old haunts. Oslo/Drammen in Norway has so much natural beauty and a really good vibe to the place.
I've uploaded my photos from the 3 week trip here, and when I'm in a bit better shape write some comments on each one.
