As someone who also struggled with meth a long time ago I’d still say nicotine.   With meth all I had to do was just to get away from everything.     Thankfully I had an opportunity to move to a different state, which I know not everyone in that shit ever have a possibility of doing, and that was enough.   Sure, I had no connections where I moved, but I moved to San Diego.   I have no doubt it wouldn’t be too hard to find some just going out looking.  And I never thought about it. Eventually came home to visit and was around it briefly and had zero interest. 

But a god damn cigarette?  That’s got a way stronger hold over me  and I don’t smoke the cheap shit.   Even cutting down on smoking, it’s expensive.

Wellbutrin made it surprisingly easy for me to quit smoking. It does something to your nicotine and dopamine receptors which makes it lose its soothing effect while making it taste less good. You might miss it slightly the first week or so. But then it's gone.
