Japan... 2 sleeps to go!

OMG I hate packing - I am utterly utterly useless at it, each time I think I've nailed the weight issue....nope... still too heavy.
As a big treat I'm getting to fly premium economy from Auckland to Tokyo.
I realise there are many of you out there that travel this way as a matter of course. Unfortunately I'm not one - so this is very special.
I can't sleep on planes and don't travel well either so hopefully it will mean I land a bit more rested than usual.
Can someone please develop a safe system where I can be knocked out and woken on arrival at destination - that would be perfect!
Beam me sideways Scottie!
