Why do i wake up each morning feeling hungover? i haven't drank a drop of alcohol in over two years, i also can hear a pulsating noise in my head

Migraines: you are waking up with a migraine headache. It may just be something prone to,perhaps it may happen because you're not getting a good night sleep. For example, individuals with sleep apnea do not get enough oxygen at night when they're sleeping, and just wake up with amigraine. I would go see a neurologist. If you're tired during the day, you may need a sleep study.
