I've been experiencing migraines since I was 3 years old. Apparently I inherited this from my father.
As I have gotten older, my migraines have become more frequent, but more manageable.
I am not on any prescribed medication (as they are only once every two months).
However, when I do get them, my first indication will be a complete elation in mood where I am super happy (this I never clue into until after I get the vision blurriness). Then I start to loose a bit of peripheral vision. Once that goes then I get the complete aura (which gives me 30 minutes to take some sort of medication/caffine, etc.). I am completely drained, and as long as I get the medication in, I will only be exhausted from the aura. If I do have a headache I won't normally notice it. There are times, yes, that I get the same symptoms as you, but on other occasions, my brain completely does its own thing and I can barely stand the glare from a dimly lit light bulb.
I do hope you are able to come to some sort of conclusion with what you are going through.
Best of luck
