I know that there is a period before a migraine. Like you can feel it coming. This is the time where you have an aura or cravings. Mine lasts from a few hours to a day in advance. Then the migraine. Then the post dome. I call it my migraine hangover. It lasts all day after, whether I have taken meds or not. I know the barometric pressure is one of my main triggers. And my head can call the weather even before I see the news. I try to avoid all my triggers. And I try to drink plenty of water. But if the barometer is in a low pressure or waving I can feel it without even looking.
I am working on keeping my diary up to date and keeping an eye on any new triggers I am going to add to my list.
Wish you all a great day.

I always have like a hang over the next day if it's really bad

Yup!

My doctor calls the before period prodrome and the after period postdrome. For me, I get edgy and angry prodrome, then anxious and tired afterward. It's terrible. Sometimes my husband can predict by my mood when I'm going to get a migraine within hours by when I start getting angry over stupid stuff or start getting ridiculously pissed off about something like, "Nobody gives a crap about keeping this kitchen clean but me!" out of the blue because one tea towel is out of place.

I get post migraine blahs, pre migraine yucks, and the big boomer during the cluster headache. It feels like you are just getting over it and it starts all over again. This summer I feel like I have spent more time in my dark room than out in the sun. My freezer keeps more ice packs than ice cream. And I sometimes see my family in passing on my way to the throne, or medicine cabinet. I can only hope that my visit to the neurologist/headache specialist can give me a new “lets try this for a few months” so I can get some relief!
