I made the mistake of drinking 4 or 5 cups of coffee yesterday, as I was home all day for a change, and spent most of it in front of mum's computer trying to catch up on as much as possible since my own PC has not been able to connect to bigpond in over a week! I had cut right back on my coffee prior to yesterday - no more than a cup a day - so all that caffeine had a huge effect. I didn't get to sleep until well after 3 am!
Around midnight I decided it was useful trying to sleep, so I got up and got a number of things done. I had a good clean out of my bookcase and a few other things. Hopefully I can continue sorting through things at home, getting rid of things I really, really don't need anymore... simplify my life!
