Oh yeah, opium would probably work GREAT for a teething baby! Hahaha! (seriously would have considered something like that just to get my daughter to sleep during her first 2 years of life....).
I used Jack Daniels - just rubbed it onto their gums. I don't drink at all, and never even have alcohol in the house (I don't like the taste of any of it), but I did have that tiny little bottle just for teething.
