yeah, honestly no point trying to nap/sleep now, its only 3hrs 30 minutes to the actual opening and I'd imagine you want about 25 minutes before it to get yourself ready to double check credit cards etc and then refreshing to see if they open one or two minutes early.
I've tried in the past telling myself at this stage that 'I'll just sleep 3 hours' and set an alarm(s) and wake up for uni. It hasn't worked and I've slept all the way through them to about 3pm!😱
If what I've read that (from the ip5 preorders) that they don't sell out until about 30-35 minutes, it doesn't sound too hard!? I'm well prepared for the site to go down, but surely it can't have a 30 minute downtime.
