I'm pretty sure Zyban is no longer prescribed.
Other stuff is, though. A coworker of mine just got something prescribed. It sounds like a brand of dog food. Champion, Champy, something like that.
Suggestions for the OP:
i) Stop thinking of it as quitting. That sets you up for failure from the start, because you're labelling your goal as failure. Maybe worse than failure - quitting can mean you didn't even really try. If stopping smoking is quitting, then smoking is success. You're getting your labelling completely the wrong way around. If your goal is to stop smoking, then it's smoking that is quitting. Yes, it's just psychological and it might sound silly, but the main addiction is psychological so it isn't really silly at all.
ii) Yes, the main addiction is psychological. The physical addiction lasts only a few days. Bear that in mind if you go cold turkey and suffer withdrawal symptoms - it won't last long. Just a few days. Hang on for a couple of days and that part of the addiction will be done with.
iii) Distract yourself, especially if you associate smoking with something else. If so, make yourself start a different association. Maybe, for example, you always smoke after eating. Instead, make a habit of doing something else after eating. Anything else, doesn't matter. The point is to overwrite one habit with another. "Habit" sounds like such an innocuous thing, but habit is surprisingly strong. Perhaps "psychological addiction" would be a better term. Drinking is a particularly big problem for this - alcohol chemically suppresses your will as well, so you get a double whammy. If you do associate drinking and smoking it might be worthwhile not going out drinking at all for the first couple of weeks.
iv) Show me the money!
Actually, show yourself the money. Work out how much you spend on smoking and how much of your life you are spending working just to pay for it. It'll be more than you think. This will help bring it into perspective:

Put the money into something. A bank account, a big jar in your front room, whatever. Watch it accumulate and spend it on something fun. For example, a coworker of mine went on a nice holiday for 2 weeks. You could easily be spending £2000 a year on smoking. That's a fair chunk of fun money. Fancy a new high-end PC every 6 months? Would you like a 42" HDTV?
v) Work with people who have been smoking for years and are older. Watch the pathetic, stinking druggies struggle to get enough air to climb a flight of stairs. Then hear about their funeral. It'll put you right off. We're not talking about small stuff here.
The patches and gum don't give you anywhere near as much nicotine as the fags. What they do is help you just enough to crack the habit.
