it's probably too late to add 02 unless you have a way to do it sanitarily. The biggest factor should be temperature. Low 60s makes many yeast sluggish, which would explain your situation. At this point I'd put it where it can be close to 70 degrees so it can finish before the alcohol hurts the yeast too much.

Wait. You're not talking about beer, right?
You're talking about beer. That could have been a whole lot more fun.
