another 24 hour fast - mission aborted

I decided to pull the plug on this fast after just over 6 hours.  I took a nap after work and woke up feeling weak.  Of course this is expected with a fast.  But for a novice like me to be in that place after 6 hours did not bode well for the next 18.  I had a lunch-size meal and am now feeling better.  So I'm starting anew as of 7:20pm and will go through the night and then see how I do tomorrow.  This was my first attempt during the work week.  I'm not going to draw any conclusions except that today wasn't the day.
