Definitely not. I've barely slept this week. I didn't get to sleep until 6.30am yesterday and I was back up by 8.45. It's 1.15am now and I'm not even slightly tired and I'm supposed to be meeting my dad in the morning. Ho hum.
Is your 'A' key working OK? (Mine is not, and I'm having to go through each message and hammer A to get it to work. I can't be bothered taking my laptop to pieces at this time.)
