I've been practicing with the bullet a bit more, and I'm starting to like the convenience better and better. Yes, it's still shoots a bit too far up my nose occasionally - usually on the first sniff - but it damn well works, it's discreet, and there's no mess, as TB said.
I have a bullet with Toque Original in it, and it certainly provided a strong nicotine kick for me. I'm usually prefer flavour over nic content, but with the terrible weekend that I had, it sure helped calm me down somewhat.
Just take it slowly, and try taking your first sniff with the nozzle of the bullet somewhat away from your nose until you get comfortable with it.
