I didn’t recognise most of my attacks as migraine, I’d describe them as ‘vestibular attacks’. But yeah for me they would last a shorter time - 2 to 3 hours sounds about right. Unfortunately the fallout/hangover could last 2 weeks.
I did get migraines for a phase, but they would last hours and hours and were truly shocking (I had to lie still and stare at a point on the wall for hours or I’d throw up), my head would get very hot and I’d have this throb at the back of my neck. Amitriptyline cut those short.
