Today is Sunday.  I better enjoy the weekend as much as I can because tomorrow morning I have a combined PET and CT scan scheduled.  I used to be one of those who got sad toward the end of Sunday knowing that the weekend is over and that all too soon the alarm clock would be ringing to herald in another Monday and the start of the work week.  Boy, I wish that was all that I had to face this upcoming week.  A work week is nothing compared to scans and doctor visits and infusion treatments.  I pray the scan goes smoothly without too much trouble finding a usable vein and that I can stomach the awful contrast drink... and that the scan results will be good....
