I'm in so much pain can't sleep, what long term damage can alcohol poisoning cause?

You mean, other than: Killing you or causing permanent brain damage? You need to see a physician, either your pcp or a pain specialist to look for the cause of the pain, and appropriate ways to treat it. Alcohol intoxication may temporarily cause you to fall asleep, but there often a fine line between the amount of alcohol that causes sleep and that which causes coma and death.

Go to ER: Or see your doctor to diagnose and treat the cause if the pain, do not self medicate with alcohol.Alcohol poisoning can cause death brain, liver and kidney damage, pancreatitis. Gi bleeding........ S.
