NOTE: DO NOT DRINK ISOPROPYL ALCOHOL DESPITE WHAT I AM ABOUT TO WRITE. IT IS STILL VERY UNSAFE AND YOU COULD DIE DESPITE WHAT I HAVE WRITTEN. I AM NOT AN EXPERT BUT AM KNOWLEDGEABLE ON THE SUBJECT

Actually, Isopropyl isn't very deadly (BUT STILL IS DEADLY). That being said, even small amounts will cause you an extreme amount of stomach discomfort (i.e. horrible projetile vomiting, diearreah [spelling], etc.), you will feel extremely disoriented (think being drunk in a bad way), and it will be converted to acetone by your liver, giving you extremely fruity smelling breath.

Ethanol is normal drinking alcohol, it's safe to consume if you don't over do it.

Methanol is a terrible thing to drink or inhale. Methanol (found rarely in some rubbing alcohols and more often in denatured alcohol) will be converted to formaldahyde by your liver, which in turn will bind to your optic nerves causing blindess. Under no circumstance should you consume methanol, ever.

All (pure) alcohols evaporate fairly readily in the air. Chances are there isn't any isopropyl alcohol left, or if there is it is in small quantities. If there was any isoproply alcohol left, you'd know right away because it would immediately combust into a high temperature flame which would cause severe burns, if you were inhaling that it'd really suck. The best solution if you are really worried, would be to rinse your peice with water. The alcohol molecules are extremely attracted to H2O so it will carry any remaining alcohol out with it.

Again, just in case for everyone's protection:
