I had a never ending headache on Dayvigo. It is a commonly reported side effect. I had to come off of Dayvigo for this reason. I also did not sleep enough on Dayvigo, but that might have been due to waking up early with a headache. Maybe if not for the headache, I would have slept longer.

The headaches were so bad that I ended up going to urgent care. There the doctor asked me what medications I had recently started and quickly pinpointed Dayvigo as the culprit.
