Why do I lie so much when I’m drunk?

I’m not new to drinking or anything at all but when I get really drunk I just make shit up and I usually regret it the next day because some of the things I lie about can actually have some negative affects (like for example I saw X and Y make out). Nothing too insane but just like stupid ass lies for NO reason whatsoever.

Otherwise, I’m a very decent drunk, I’m never violent or aggressive, I don’t really cry, I have a good time, I don’t black out and I don’t get handsy etc.

How do I stop this? I’ve tried to tell myself when sober to make sure to not lie when I’m drunk but I can’t seem to help myself. I don’t make shit up like that when sober.
