Don't get impatient. Recovery from major surgery can be slow to ponderous and even unpleasant according to my body, and that does not include the impacts of laying in a bed (1 day will take about 7 to overcome) and anesthesia (which takes a long time to process and get out of the body). The first month I was exuding crud from the anesthesia, and while much better, I am not bonebreaking it down. I am roughly 6 1/2 weeks downrange from my kidney transplant and there are still some lingering effects even though the process went well and in many ways I am already better than I was on 7/17.
I have developed a lot of faith in the medical care I have gotten and the knowledge and proficiency has improved by a lot from the mid 90s when my Dad had his heart troubles, eventually fatal. I am hoping that you can find faith in the process similar to mine.
