Hmm ... I did another Google search, this time on Zyban. Most of the top links that came up were companies selling the stuff - a lot of marketing hoo-hah. I was looking it up because I know of someone who used it to quit smoking (this seems to be its primary function - a stop-smoking medication).

Unfortunately, people who have seizures are cautioned about the drug. It's not recommended for those people and as I am one of them, looks like Zyban is out for me.
