I'm guessing he is actually zonked and dronked. It's a pretty common thing to travel while intoxicated, to alleviate the boredom and/or anxiety of travelling.
Anytime Ralph 'leaves town' he gets plastered and pilled.
All those benders he did with Andy whenever they travelled, the Portugals, the celebrated Rome flight, Vegas Cardiac Event, the Return from Vegas crash, drunk driving around DC, weed dispensary credit card reveal, The Blaze Studio Strut, the truck break checking streams, Ralphamania, all the driving to the airport truck accidents in Messiko, the AF Breakup Flight, Goodbye Horses at Dick's place, recent Xanda and NY stuff. I'm sure there's more.
as a matta a fak, the only times he made an effort at passing 'sobriety' were those phases where he was sitting all alone, texting away while MSM or street food clips played in the background -- and even the most deluded Bobs of the worlds had that Sober Fantasy shattered every time he tried to initiate physical encounter with Deni.
For a while I wondered if it was travel anxiety or something that made this happen, but I think he is just a cowardly little baby NEET that mommy coddled for 35 years and he is terrified of going outside where the cool kids will give him wedgies and swirlies, and expose his micro to the Stacys that will laugh at him after sending him fake love letters.

You'll never be the next Chris Chan, Ralph. Chris mostly raw dogged his comeuppance.
