I have no PTSD, but I recently lost my job, and while I am looking for another one I decided to use the time off in order to stop smoking, so far it's been a bit more than 3 weeks, and I think it's been the period I've been playing the most videogames in high school, it is really useful to overcome temporary cravings by doing something that doesn't require much mental efforts but still keeps the mind busy to don't think about smoking, every day I am suffering less and less, and I think without videogames it would have been much harder
