As a rule, no.
It might be you'll find you need insulin for your beer, but if you take it way after drinking, so when you get home, you'll run a high risk of going hypo in a couple of hours.
If you need to inject for your beer you need to do it like you do with food, so before, and not hours later.
The alcohol by itself might make your blood glucose drop through the night, adding a late dose of insulin to that sounds risky to me.
Is this a situation you're in right now? If so, how high is your blood glucose?
