Ken,
Your fatigue is going to be due in part to the oxy, it depresses the central nervous system, slowing the cardio vascular system which causes physical fatigue due to lack of blood circulation and lower oxygen levels. Opiates also constrain testosterone levels making recovery harder and causing fatigue. Just as an fyi. Any weight you lost during treatment will primarily be lean muscle mass, meaning you have less skeletal muscle to support your frame, and you've certainly been exposed to highly elevated Cortisol levels due to the cancer experience. So the fact that you are only slightly fatigued is a good sign.
OCF has been the leader in
HPV awareness and vaccine advocacy in every way, and putting money towards research in it for a very long time. Brian Hill has been at the forefront of
HPV awareness, vaccine advocacy, and education, it's a huge hill to climb so when you're feeling up to it jump on board. Those of us in the fight could use some help.
