Hi, my family doctor put me on Doxepine for my migraines as they have been frequent. I also just came off of birth control because we are not sure if that was what was causing the migraines. While the doxepine seems to be working already (after 4 nights of taking it....at 10mg per pill) I feel sleepy all day. The first day after taking it, I felt like I was high, the second day I felt as though I was hung over, and since then I have been tired all the time. I have been sleeping about 10-11 hours and am still tired. This is very unusual for me. Could it be from the medication?
