Nyquil does have a high percentage of alcohol--not a good idea for an alcoholic.
As to mouthwashes containing alcohol--that isn't clear-cut. Some alcoholics have been known to drink it, and others are uncomfortable enough with the idea that it is best avoided. Others (like me) don't have any qualms about using an alcohol-based mouthwash. That's pretty much an individual decision.
Same with alcohol cooked in food--some say it's OK, others not.
Up to the individual. I always suggest that anyone in doubt should avoid it.
