Hi JK, Volunteer Mentor @contentandwell I'm a pre-transplant patient on deferred status until they investigate constriction in my carotid arteries. I stay tired now. After I wake I have maybe 2 hrs of energy, which I use to get things done around the house, go to the gym, groceries, etc. Then I have to lied down until I get a second wind about 3 pm until 5 pm. Then a Major nap as I'm deep down exhausted - after which I'm up until 2 AM and I never sleep more than 4 hrs at a time. I was hoping this would go away. My Doctors are at the MAYO in Phoenix and this is another question to add to my list as well as I'm hoping to meet with a support group to get the opinions of people that have completed the operation..
