My daughter says that I fired her, but I said no, I just cut your hours. I have told her many times I could not have made it without her, she pulled me through many tough times. I am so grateful. Now I have a few questions on my own. How long do you still have heat in the knee. I was 10 weeks two days ago and at times my knee is warm. Not as hot as early on, but still warm enough that I put some ice on it. At night is gets hot and may be part of my sleep problem. Just have a terrible time sleeping. After two hours when I may or may not have slept, I wake up wide awake with no sleep in me until 2 or 3 in the morning. If I take an aspirin I may fall to sleep by 4 and at best get 3 hours sleep. I rest a little late afternoon may cat nap 20 or 30 minutes, sometimes do not sleep and by 10 at night I am tired. Don't suggest sleeping pills, or supplements, I won't take them.
