I am in a bit of a panic because tonight I guzzled an entire bottle of white wine with my burrito.

I did not intend to get drunk.  I got overconfident and figured that the burrito, a giant beefy concoction known as the El Diablo, would soak up all the alcohol.  I wanted a sip of wine with each bite of burrito.  By the time I was done, there was about 1/6th of the bottle left and I figured I might as well drink the rest along with the salsa and chips.

Without realizing quite how drunk I was, I got the dog and took her for an hour-and-a-half walk.   When I got back, despite the long, brisk exercise, I was unable to say the Rosary. My lips were all numb.  I had to confess to myself that I was pitifully soused.

Basically I was stupid.  A full bottle of wine will get anyone drunk, let alone a gangly stick-figure like myself.  But I figured for some reason that it wouldn't affect me.

I'm the type of person who, at the worst, becomes a little more goofy and friendly than usual when drunk.  If you know that the WORST thing that happens if you get drunk is that you get dizzy or sleepy or goofy, is that still a mortal sin?  How drunk is mortal-sin drunk?  I had a friend who got  so drunk once that he went up to a random girl and punched her in the face.  That to me is DRUNK.  I know of others who "drink to forget," who deliberately try to obliterate themselves.  Lots of others fornicate or fight.  I never get even close to that state and so for me there is almost no sense of sin involved in drinking.  Perhaps that is what's dangerous.

But can I say I "accidentally" got drunk when I drank a full bottle?  

If I were at the Saddleback Lodge consuming an entire buffalo, that might have soaked up the alcohol. ( Private joke -- Alex and I both live in Los Angeles ).

You answered your own question here: "I did not intend to get drunk. I got overconfident and figured that the burrito, a giant beefy concoction known as the El Diablo, would soak up all the alcohol."

And there's of course the whole "occasion of sin" angle.  Some people are more prone to committing sins of impurity or anger when they're drunk.

Your culpability rests in how reasonably sure you were that you would not get drunk.

You had no idea that drinking a WHOLE bottle of wine would get you drunk?  If you considered this possible and did it anyway, then there is A LOT more culpability there that these guys are admitting.

But, I believe, then it would only be a venial sin on his part.
