Yeah, I didn't mean the specific drug. I imagine that habits generally work by needing some chemical to act as a reward to reinforce it, maybe different chemicals for different habits. The idea of forming a good habit to preempt a bad habit with something that will block the reward chemical, whatever it is for the bad habit, is interesting, and I wonder how generally it can be applied. Like, I wonder if it would be an effective idea to block dopamine or another chemical to help against bad habits related to computers/internet or food.
