I had a PLKR on August 12 and I think I'm doing great as far as most things go. I'm down to 5/500 maybe 2 or 3 times a day on Vicadin and a double dose of Naproxin every day. But I don't understand the "on and off" switch in my body. I went back to work at about 5 weeks and have been there every day for at least 6 hours if not more. The last week or so, I've had terrible bouts of "shut down", where I'm so sleepy at 10 a.m. I can't function and end up having to go home to sleep (I live next door so that makes it easy). I have tried more sleep, less sleep, naps, etc. I'm exhausted during the day but can't sleep at night well. I've tried to stay up past the drowsy stage (usually between 6 & 7 p.m.) by keeping busy doing something. I'm not in much pain. Isn't it a little late in recovery for me to be experiencing these things? And shouldn't I be pretty much pain free by now?
