My husband for a long time has periods of extreme exhaustion, I mean sleeping 18hrs a day for 2 or 3 days, just general malaise and lately episodes of nausea, dizziness, and vomiting. If he has a headache it’s usually pretty mild. After a million tests they think he may be having migraines. He was started on Amitriptyline to take daily. I’m guessing it’s rare to have migraines without headaches but is it impossible? Although now that I think about it he has had headaches but we usually attribute them to sleeping so long with out drinking anything. I don’t know, it feels overwhelming to treat something that is hard to actually diagnose for a certainty. And also does this medication seem to really help people? Thank you!
