A friend of mine managed to quit by selling his PC computer. He found that being unable to play was the only way to be sure, and that it's easier to sell a PC than it is to not install the game or not play.
Not sure if this is good advice or not.
Selling the PC and going to mac is great advice. Many times I feel a small temptation to just go download/install and set up my keyboard shortcuts again because it would take just about 1 hour. If I had to buy a new PC to do that I wouldn't even consider it.
The problem is that I'm a C# developer, and even though it's now possible to develop .net core in a mac without issues I don't think I want to do it. Also I find macs extremely expensive, my ThinkPad is a beast in specs and costed 1/4 of an equivalent mac. Well of course it's also uglier, heavier, makes more noise and spends more electricity than a mac, but I'm ok with that, I like my computer ugly on the outside but performant in the inside :)
