The other major nicotine replacement product is the Nicotine Lozenge, and the most popular brand name is Commit. Personally, the lozenge is my preference. I'll admit that, at first, it doesn't always taste that great and can feel somewhat strange in your mouth, but after you get used to it, some of you (like myself) may actually like it almost as much as smoking. It's basically just a mint that you stick in your mouth that generally last around half an hour or so. It tastes pretty good after you've had a few, it doesn't leave canker sores like the gum often can, nor does it leave the weird aftertaste that the gum does. Moreover, though it doesn't solve the hand fixation, it will satiate your need to have something in your mouth. I'm a big fan of that, because for many people who quit smoking, you're inclined to replace cigarettes with food, and at least while the lozenge is in your mouth, you can't really eat. So, in a way, the lozenge doubles as nicotine replacement and helps to curb your desires to munch.
A few warnings, however: 1) In my opinion, the lozenge -- because it offers few drawbacks -- can be pretty addictive. I was actually on the lozenge for around two years before I was able to wean myself off of it with the patch. And 2) sometimes, they can cause hiccups, if you suck on them too fast. Also, whatever you do, don't swallow them, otherwise you're in for about 2 hours of hiccups and probably a pretty bad headache.
Overall, however, I give the nicotine lozenge a solid A-.
