idk man, i've had 2 migraines in my life. that shit is legit crippling for some. I was so light sensitive it felt like an icepick in my brain and i was vomiting as a result of light exposure. Like bad headaches whatever, pop some aspirin and move on, but a migraine is like something inside your brain is swelling and trying to explode some anheurysm or some shit idk. it's god awful. That being said, pot works for that.
I have bad headaches every day. It's just something you learn to live with because no fucking quack in this world is going to be interested in finding out why unless the why pays them more than shoving pills down your throat.
99% of headaches are from dehydration. Everytime my head hurts, I drink a glass of water and it's gone. Idk birds might be different tho.
I drink quite a bit of water. Usually on the order of 2 gallons or so a day.
