If your thinking about mixing them and drinking them that would be a bad idea. You'd get sicker than you could stand and the buzz if any would be minimal. VERY BAD IDEA!!!!
No.
No
Just did we shall c
Yes you can. I just did.
i mix it all the time, and its never given me problems!
Not much, and if you trying to get a buzz then your a retard. The DXM in it is what gives you a buzz, and its VERY unhealthy to take more than the recommended dosage of it. A bottle worth probably wont hurt you but theirs a good chance you will get sick and wretch everywhere. Just leave the NyQuil alone.
I don't know you well enough to give you an answer, call your doctor. Do not mix without his/her approval.
Yes, if done within a short amount of time. I have seen guys fail a BAT if they had used mouthwash within 15 or so minutes of taking a BAT.
Some people use a sodium solution as an antibacterial mouthwash to combat microorganisms that cause sore throat or inflamed gums
Though it's hard to say, depending on which NyQuil you would use, as each NyQuil has different drugs and a combination of them in it (NyQuil Cough, NyQuil Cold & Flue, etc.), it doesn't seem like there would be an interaction between the two.
No. Just use an alcohol-free mouthwash.
I would think yes when you mix it with water... But it would dry your mouth out.
