Bonnie is nice to have but it's quite difficult to use and it's a commandline tool.

For the non technical:
You start sampling carlsberg beer to find out how quick you get drunk, using a tiny straw full with holes. After awhile you're only slightly tipsy, and quite angry because other people drinking light beer passed out already, and you suspect they must have stolen your carlsberg or mixed yours with water secretly. (In fact they used a beer bong)

It would be really helpful to everyone, if a summary of your experiences (good and bad) were posted on this thread or this wiki section.
