I want to puke in the sink
What makes you want to use the sink instead?
I want to know if I can still do so while being drunk.
Drinking until you vomit is something that seems to be your goal. That is so messy and shouldn't be done where there are dishes to be washed. Instead vomit in the trash can or toilet please.
Who cares. I want to know if it's possible to puke in the sink.
I think that you are going to regret it though. It is going to be hard to clean it up in the morning.
