It went pretty good today. I got there at 9:30 am and left at about 3 pm. I was hydrated so no problem with the needle. I didn't have any site reaction or any other reactions at all. It was almost as if they only gave me saline only for 4 1/2 hours. The worst part was having to sit in a recliner the whole time. I have lower back problems and it was causing my legs to hurt. Had to get up and walk around a bit a couple of times. The only thing I have noticed since I got home was, I haven't been able to sleep. I think I dozed off for about 30 minutes and that's it. I go back for part2 on the 25th.
