That's tough man, but I am sure you can do it. The key is changing habits. Which is easier said than done I guess. But maybe your gaming will work.
I was going to suggest Snus. I don't know if you have the same name in Finland ? But yea the tobacco that is in a pouch that you put under the lip. It's not supposed to be near as harmful as cigarettes. But still it would be replacing a bad habit with another bad habit so haha forget that - stick to the game plan ;)
My roommate has snus and offered me some to make it easier, but I think I'm going to stick to nico gum instead. Might use it a couple times if things get really tough.
My husband started smoking when he was 14, and smoked until the day he moved to be closer to me when we were dating. He quit cold turkey, because he knew how much it meant to me. I will be honest when I say he’s the only person I have come across who did not resort back to smoking, but it took him a few years to ditch the immediate desire to smoke when around others who were smoking. For the last couple of years, he has been using snuss and likes it. Gives him that little taste of nicotine without chewing gum and a plus side of not smelling like other tobacco products. Like @gtrplayer said, keep fighting the good fight. One of the negatives of quitting smoking is trying to replace the oral habit- the actual movement of taking the cigarette out and bringing it to your mouth. Replacing that with chewing gum, straws, toothpick etc will help a lot with that desire. Gaming is awesome too to preoccupy your thoughts :) good luck!
I think you make the right decision, it's not a really sexy habit to snusa
I didn't use snus, but I used to chew. You don't want to get going on that stuff instead. better to cut it all out.
