I enjoy cigars and notice the positive effect, my fear with the patches or Lucy/zyn is that it not being self limiting seems to lead to people having one in their lip literally every waking minute when they’re not eating.
I sometimes realize in the afternoon that I forgot to change my patch in the morning because I'm a bit drowsy (a feeling not unlike being uncaffeinated when you're used to drinking coffee). AFAIK the withdrawal symptoms fade out in at most a week.
