You can drink on Keto.. but it has to be straight liquor.. vodka seltzers are perfect, canned spiked seltzers also work. No other mixed drinks or beers though.
I had several shots of tequila and four mixed drinks. At some point I lost my pants and locked myself out of my friend's house. I was still sick until like three hours ago. I think I'll just be skipping alcoholic beverages of all kinds until this fall. XD
