I have recently started being woken by what i can only describe as a surging headache in the early hours. Since Christmas i have had one every 3 to 4 days. Takes ages to get back to sleep and the next day is a washout as the headache lingers. I have recently come off statins, i wasnt taking them for long. I already take amitryptiline at nught but these are not helping. I told the doctor but she put it down to anxiety, which seems odd as they are so regular. Has anyone else experienced this?
