When I wake up in the morning it s so painful to week up. Despite sleeping for over 10 hours,it feels like I ve slept for only 2 hours. I m extremely groggy,fatigued,eyes hurt and I want to go back to sleep. Naps do not feel refreshing at all and after waking up from a Nap I ve same symptoms. This problem started after I was prescribed doxepin 10mg for headaches, I only took it for two weeks because the oversedation wad so bad but the oversleeping is lingering till now. I took it about 5 months ago. I always go to bed early and at a particular time. I can t stay up past 11 and I HAVE to be asleep by 11. Sometimes this problem will dissappear for days then come back. Is the doxepin responsible for this or is something else wrong?
