Just drink ginger ale. Looks enough like booze, that people don't bother you.
And I avoid drinking sugary drinks all night because they’ll give me a headache.
My main concern with it as a substitute is that you get through it quickly and rack up the sugar levels in no time. Best bet as far as I'm concerned are 0.0% beers - a third of the calories and a fifth of the sugar - although I'll try to stick to two of those at max. They make me feel groggy despite having no alcohol in them.
It's a non-issue.
Why?
I don't like jail. It sucks.
