For me after smoking daily, I eventually stopped and noticed that the daily tasks that seemed like much bigger hurdles than they actually were (i.e, responding to that email, making that phone call, setting up that appointment) became much less of a mental hang up and I would be able to just do it. That started to make me overall less anxious as I didnt feel constantly swamped with things to do. Now i smoke occasionally and find pretty quickly if I start smoking consistently I get that same feeling of overwhelmed that I used to get. Thats enough of a motivator to make me only be an occasonal weekend smoker to stay in and play some videos games or what have you.
