Yes, but also no. Through practice alone you do get better at activities while drunk, like walking or driving, but I can assure you that what two drinks did to me when I never drank vs what they do now is entirely different. My rationality stays the same now. Note that the high alcohol content will catch up to you later (you’re still dehydrated), but in the moment alcoholics are an entirely different breed a couple drinks in. If you ever hang out with people who drink regularly and those who don’t, you’ll quickly see the difference.
