It's understandable that people would be concerned about their loved ones being so drunk that they are "stumbling" and "falling all over" and might hurt themselves. Especially since it's a regular occurrence. It's dangerous (falling all over cant be that good). Plus heavy drinking damages internal organs (liver etc).

Also it's concerning that you believe you are only "true self"
when you are drunk. So why can't you be yourself sober? So you can't be true self when you are sober?

Also is your "true self" falling stymbling and vomiting on yourself and falling asleep in public place?

Have you Considered talking to a professional? Therapist or doctor?
