I've been trying the South Beach one for a bit now, and I can't say I'm a huge fan. It definitely quells the "craving" for nicotine, but I think part of my love of cigarettes is also the burn, which they don't give me. Also, the flavor of the "regular" tastes nothing like a real cigarette to me... and I like the flavor of cigarettes. I'm trying them out because well... I'm sick of getting harassed by girlfriend and family to quit... ha. So I'll stick with them for a while and see if I start to enjoy it. Although I'd love to try out other flavors besides what South Beach offers...
