I have been addicted to Pokemon before, but not to the same degree as my addiction to this
site. There will be several months straight where I don't even play the game; heck, I haven't played a single OU or Battle Spot match the entirety of SM. During those periods though, I spend a lot of time checking Smogon whenever I get the chance (public restroom breaks, work restroom breaks, etc) ... not even participating. I'll just scroll through suspect threads or cong threads that I don't give a shit about just because I love the website so much. As a part-time teacher, I wasn't given any classes last summer (despite being more than capable of teaching the material, my boss made some shit up about me not being able to teach upper division classes despite the fact that he had let me before). I was completely unmotivated to actually get a job rather than sit on my ass mooching off of the people I live with. Hence, I spent a lot of time on PS modding the OU room and participating in their policy decisions, making myself absolutely miserable by thinking "wow, look at all my friends from hs and college, moving on with their lives, getting married, getting promotions, having kids, etc." Then in August, my grad school loans caught up to me because I "never got around to" paying them monthly. I was able to pay what i owed at the time and survive the rest of the summer off of my own money, but it was really tight. Something had to change.
I had my gf hide my 3DS, had my friend
Jellicent gray out my badges, asked to be demoted on PS, and quit cold turkey. I would check the site every once in a while without logging on, which helped because I get to see what's going on, while detaching myself from the community by not participating. Thinking about the game made me sick to the stomach because it was a reminder of what it led me to, so I didn't even have an inkling of a desire to play it. In the mean time, I did an overhaul of my resume, made myself a template for it and cover letters in order to make customization very easy. All of the sudden within the span of a week, I had applied to 6 jobs, which is more than I had applied to within the previous two years combined. I started getting phone interviews, and eventually landed a very well-paying job. Sun and Moon came out and I asked my gf to reveal the location of my 3DS as a "reward." I haven't completely lost the desire to play, but I'm definitely past the addiction point. It probably has something to do with the fact that I'm constantly doing something. Pokemon has finally become a spare-time thing for me instead of a MUST PLAY OR I'LL DIE OF BOREDOM thing like it was for a long time.
Basically, don't let yourself get to my point. I delayed life for a lot of years from my dedication to this game and this community. You don't want that to happen to you, trust me. Is quitting cold turkey the right thing to do? I honestly don't know; I've tried it with Smogon and I always eventually come back. I like
Pidge's idea of setting time limits (don't ask for a month ban though, lol). Set a really annoying alarm on your phone, keep it next to you, make some simple goals for the day, and do those things. Enjoy school while you still can. If you still have a chance to pick up your grades, do it. Talk to your family. In the words of J.K. Simmons, "call your mom."
