Chronic migraines...?

so i get chronic migraines. and i get em bad. the auditory hallucinations, the anger, the throbbing pain in one side of my head (usually the right side, the pain makes my eye droop too), and i'll always smell or see something that's not really there. the pain and side effects always last hours. especially if i get them in the morning, they last until i go to bed that night. taking strong (otc) pain pills and drinking things like coffee with a lot of caffeine help, but the pain's always still there. i'd rather not have to get something prescribed or go to h doctor, but idk what to do and i need help on how to deal with the pain and side effects. please :[
