Thank you all. He is the protagonist in a first-person novel (talking to the MC, so we are not in his head).
I've already shown him drunk - jerking as he slipped down a wall, etc. and then told the reader his speech sounded blurred (yes, I like that word!).
The MC is fearful as she hears his voice rise, we see him click his fingers to try to remember someone's name, etc. From feedback in a recent critique, it said his speech needed to indicate the drunkenness. So it's just the one para of speech I'm struggling with.
I'll have a look at the confused speech, without losing the point of what he's saying. It's difficult with this being page 2, as I'd have a bit more freedom with the characters later on...
Actually, in the middle of responding to your really helpful feedback I just had a lightbulb moment. Thank you. Got it. Wrong character name. Thank you
<Added>Can I point out, that the confused final para does not show I have been drinking
