Chocolate: nice flavor, cocoa more than chocolate to me, and a bit wimpy IMO, but again that could be the m401.
Raspberry: very nice, smooth, fruity goodness. Very nice with coconut.
Lemonade: tastes like homemade lemonade, with a bit of lemon zest flavor, not super sweet.
Tobacco: no tobacco flavor really tastes like tobacco to me, but it's not a bad flavor, not real strong for me, but not like much of anything else either.
Root beer: okay, this one's seriously odd. One, doesn't taste like rootbeer to me. More like a hint of sassafras, and just a hint. However, it's the first liquid I've gotten with nearly the full feel of a cigarette to the vape. I'm still trying to find something that really replaces my urge to smoke and haven't yet, but this comes real close.
Overall, I'm thinking there's something wrong with me or how I'm doing this, since I'm getting like NO nicotine feel from vaping, even when I basically breathe through my m401. I used the Nicotrol inhaler for a bit, and had more success delaying a cigarette with that than vaping (though vaping is far tastier and more fun).
