X to doubt Phil is an alcoholic. He's a lying faggot. Lied about weed parties, lied about building PC's, lied about lifting weights, lied about depression.
Just like his bad back, his supposed status as a "former alcoholic" was just a lie to get sympathy donos from dents or to avoid responsibility for his past bad behavior. He used it to avoid Jaha's wrath too. It's always about making himself into a victim so people around him will go easier on him.
I know it's funny to view him as an alcoholic but the more I think about it the more I don't buy it. Yeah 'functional alcoholics' exist who can hold down jobs etc but DSP's autism schedule is the exact kind of thing that alcoholics would struggle to maintain.
Probably an unpopular take, but I personally just think his drinking is another aspect of his gluttonous nature and not an actual addiction.
