I have used ecigs since last sept. they do the job for me 99% of the time. Still tough when out at a bar when so many ppl are having the real thing, but since a smoking ban is coming to WI this summer anyway, it won't matter. I order them from vapor4life.com, and I try all different sorts of flavors, including menthol, but my favorite liquids right now seem to be the orange/citrus flavors.
e-cigarette-forum and specifically the
Vapor 4 Life subforum are where I get a lot of my info. There's many different manufacturer's though, so maybe look over an FAQ or something first to discover what you might be interested in trying.
