Second-Choice Drugs

If nothing else works for you, there are at least two other drugs worth trying -- clonidine and nortriptyline -- and both can be used with nicotine replacement therapy, which is a definite plus.

However, there's a reason they're not first choices: They have side effects that many people can't tolerate. Still, depending on your situation, one of these options may help you kick that butt for good when all else has failed.
