Charlie Sheen videos don't get any more REAL than this -- it's Charlie totally blitzed in the middle of a late night Taco Bell run ... and he looks and sounds EXACTLY the way you'd think.
The clip starts with a totally disheveled Charlie stumbling over to a car at the drive-thru -- looks like the driver called him over -- and the Ma-Sheen quickly unloads this awesome line ... "Sorry, I'm so f****** hammered."
Honesty really is best.
Unclear exactly where and when this went down ... the clip was posted sometime on Tuesday, but it doesn't really matter.
Watch ... the Warlock rips open his shirt, shows off his tatts, and even attempts a little couples counseling.
Don't worry, doesn't look like Charlie was driving. You can see his typically chauffeur-driven Benz in the background.
