How come when you throw up alcohol it's painless but really smells bad?

Alcoholism=self dest. Beer causes stomach ulcer and nausea vomiting, along with liver self destruction. Some people are resilient and can absorb a lot without results till late. Mental consequences are disastrous to self and family and loved ones. It is deadly inherited and younger generations suffer much more than the gen: schizophrenia, severe mental problems, autism, adhd, disabling anxiety. Treat now, no option.
