What do you think i should do if i over dose on hydrocodone?

Go to an ER: A true opiate overdose would not leave you sitting at a computer typing your question. By definition, an overdose results in impaired consciousness, with at least stupor, and usually some stage of unconsciousness (coma), ultimately with reduced breathing and potentially death. If you are taking more than prescribed, or it it isn't prescribed, get some help. Talk to doctor or counselor asap.
