What do you make of people who completely change personality when drunk?

Wary of them?
I can be a pain in the arse when I'm drunk but I've been told I'm an over exaggerated and louder version of myself.
What do you make of people who get a personality transplant when they get drunk?
The guy I'm seeing is shy, introverted, doesn't say much about anything, worries about looking stupid or what people think of him by day
I witnessed him after quite a few drinks, while I was happily tipsy, he became really over confident, rude, cheeky, ie burping really loud in public, overly open etc I was taken aback - where has this personality come from and is that a real side of him that has to come out at times?! So weird.
Evveryone else I know is just them, drunk when we drink together. Ive only got one friend similar to this who changes personality when drunk and i avoid any drinking occassions with her if possible .

How long have you been dating?

I hate to say it op but mostly, drinking just makes you a more exaggerated form of yourself.

If drinking makes him insuferable and rude then he shouldn't drink. If he doesn't care about how it makes him act then maybe you shouldn't date him.

I think that if you know you are an arsehole when drunk then you should be teetotal.

Much like alcoholics who know that once in recovery they will never be able to just have the occasional drink.

I have known people who don’t drink because they know they don’t tolerate alcohol well and I respect them, people who turn into arseholes after a drink or two I have very little time for.

When I have a drink I'm basically the same person but without inhibitions. So, in my head I'd like to dance on the table but I don't, after a drink I might. In my head I've got a joke that might or might not go down well. Sober I probably wouldn't say it, drunk I would. It wouldn't be nasty though, I'm just not sure it's actually funny.

IME nasty drunks are nasty people whose inhibitions /manners usually keep them in check. For example, I've never worked with nasty drunk who wasn't also nasty when feeling underpressure at work.

I'm not sure burping and over confident are a change of personality though. Again it's just inhibitions being removed.

They don’t ’completely change personality’. Alcohol lowers their inhibitions and aspects of their real personality emerge which they keep hidden when sober. I worked in pubs for many years, and one of the main lessons it taught me was :

People who turn into arseholes when they are drunk are showing you who they really are, and the same applies to people who are nice when they are drunk.

I was like your BF. Alcohol was like removing all the things that made me shy. Suddenly feeling like I was able to talk to strangers laugh, dance and enjoy the moment.

As time went on I had to have more and more to have fun, but I was no longer fun. People either avoided me or wanted me about because of the drama I caused. I never realized I was being laughed at.

I no longer drink at all because of the effects it was having on others. I couldn't care less what it did to me, if it damaged me but I noticed that my drinking went from social to at home alone until I passed out. I wasn't a nice drunk in the end. I had an ultimatum from DP. Either him or the booze. I was angry , upset, scared how I would cope without being pissed on a Friday night. But I managed it. I've embraced my shyness and although I do socialize I do find im always the first to leave, hate dancing and despise small talk. So it's a chore rather than being something I look forward to. But not having to deal with the after effects is so liberating.

He needs other outlets, please avoid situations where booze is a big factor of the evening. Talk about it in a non confrontational way. He might be able to recognize his limits if he's lucky but I couldn't. Be strong OP. He will be OK but only if he wants to change.
