One thing that helped me most was to substitute the other ingredients in cigs (mainly the MAOIs). Had to do a lot of reading and discuss things with my doctor, but there can be other factors for those having a difficult time switching.
Wait, so your doctor actually prescribed you an MAOI to help you? Thats terrible IF true and if its a non-selective MAOI. MAOI's are horrible drugs that the scientific communities been trying to step AWAY from because of their risks for interactions, such as the MAOI "cheese effect" (google!), this is particularly true of MAO-A inhibitors or non-selective inhibitors.
With that said, a MAO-B selective MAOI such as Deprenyl, which will predominantly only affect dopamine neurotransmitter levels (as MAO-B clears dopamine, MAO-A clears serotonin/epinephrine), is likely the cats ... for aids in getting off cigs (its also shown success in helping people quit ....... and opiate habits).
Side note to your purpose for life; dopamine is what we all live for, most just don't know it. Dopafiends for life is all we will ever be, you and me
