I'm 17 days post op. I'm having issues with waking up before 11am/noon. It doesnt matter what time I fall asleep the night before, my body will not wake up. If i do manage to somehow wake up within 10 minutes i am asleep again. When I do wake up, I'm extremely weak and kind of disoriented. I have an appointment Monday with my doctor and I plan on telling him. However, does this get better over time?
