Tumor marker and tumor size

So yesterday was the big day for the Computer Tomography scan.  I had to drink 2 bottles of vanilla barium drink starting at 7:30 AM.  We arrived at VABaptist Hospital for a 9:30 AM appointment (arrived at 9AM) which really never got under way until about 10:15AM and took a total of 5 minutes.  Luckily they put the dye in by way of my port, so no wasted time searching for hidden veins for an IV.
I was very relieved when the whole procedure was over and I could go home and drink and eat.  I found out during the scan that I could have had water or even coffee in the AM but they are very picky about those things on the instruction sheet...just no food!!!! Margie drove us my faithful sister, and Agustin is always with me for all the procedures❤.
When I got home, there was discomfort for the afternoon dealing with expelling all the barium and dye but hey, those things are really nothing compared to chemo side effects these days.
Yesterday I was feeling quite good!
I received a returned call from my doctor who really was waiting until Tuesday appointment to share the results of the CT scan.
She told me the tumor has shrunk to 1.9 cm.  It started out beginning of  November about 4 x 3 cm.  So, seems maybe half the size with this particular treatment choice.  That is reassuring!  I thank God for this news.  It has been about 3 months so far.
I do have a problem though, with the way I am dealing with the treatment's side effects.  I have had some very hard days over the past 2 weeks and I have to go through it again starting on Feb. 14 again....Happy Valentines DAY!!!!  Maybe I will convince myself to take a week off and convince my doc:)   I will discuss with my doctor again if there could just be an extra week for recuperation until the next round.  I wonder what she will say and how I will deal with it?
I feel that if I had an extra week of recuperation my attitude and stamina would improve so much.
I admire so many people that I have recently known who are going through worse things than I am.
Which reminds me, the last time I was in for infusions of fluid, 3 days ago, I felt like I was dying inside...weak, lethargic, nauseated, etc.  I would look in the mirror every time I would walk to the restroom with the IV pole and wonder how it would be to be dying.  Then, I told Ruthie one of those times when she accompanied me there, "I think if I were dying, it wouldn't be this bad because I would be full of morphine, and wouldn't even know what was going on anyway:)"   Well, she told her friend Shawn who told her right back,  "you tell your Mom that is what "fighting cancer is".!  I guess as long as you can "fight" it, God is going to see you through and give the relief when necessary.  Meanwhile, today is a beautiful day!
Friends, family and my faithful husband are surrounding me with encouragement, support and good food:)
Most of all, "God is my refuge and strength, a very present help in time of need". Psalm 46:1
