Drunk you is probably overconfident in your own understanding. Personal anecdote though, in reagrd to me solving math problems. I loved being able to finally solve the problem, and it seemed "so simple" after so much time had been spent, mulling it over. And then sober me would realize how wrong I was because of a 'simple' mistake that drunk me made. I loved the "Ureka!" moments, but sober me would usually wreck it the next day

But again, that's my personal experience. Would love to know that's not your own experience. But just a friendly forewarning of "check your work more than twice"
