Here is a novel idea ...
I was in a pro-am once and I was having a light lunch before 'the off' and my amateur partner joins me at the table. He sits down and a few minutes later the waiteress comes with a tray of whisky's (4 of them) with soda.
He downs them all, eats a greasy pie with gravy ...
"To calm my nerves" he says as I sat wtaching him, trying to figure this out. it was 11:30 in the morning. "I won't even realise I'm on the tee after the other 4 I'll have just now".
