Wellbutrin and Chantix have worked for a lot of people...be careful with them both if you have a mood disorder though - I tried Wellbutrin a couple of years ago and it put me in a mixed state (worst experience ever!) My doc won't even let me try Chantix so I am stuck trying to quit the hard way

I have cut down on my smoking and I am alternating "real" cigs with an e-cig and then lowering the nicotine content in the cartridges I buy...

It's working so far but I definitely have good days and bad days...wish me luck
