Why didnt i have to get my stomach pumped after taking 20 advil with alcohol?

It's likely the hospital didn't pump your stomach because 20 Advil is not enough to kill most people. That said, taking a lot of Advil and drinking alcohol is very bad for the liver. It is a good idea for you to get help for whatever is cause your self-harming behavior. There is a Crisis Call Center you can call or text for help.
