Easy answer is you need to WANT to quit first. It's like anything -- smoking, drinking, etc. People spend all sorts of money on things like "the patch", the gum, hypnosis, etc. but unless you really want to stop. You won't.
If you really want to quit you'll go to the local bookstore and read up on addiction, go to the local gamblers anonymous, find a sponsor, cut off all your friends that are enablers, tell your friends and family what you are doing and reach out to them for support.
You most likely have an addictive personality which means you'll get addicted to anything. So if you replace it with anything like the people mentioned above, you'll find something that you latch onto and can't get enough of.
My suggestion is pick up a pair of running shoes, join a running forum, download an app like mapmyrun, and just go out and run. You'll get hooked.
The reason you don't find the other stuff exciting is because your mind is always focused on gambling and it doesn't supply the rush. Get away from it for awhile and you'll be surprised how much fun it is going out to dinner and joking around with friends.
Also, get a girl friend, if you can get one. Then find a couple girls that just like to hang out. It's much more exciting going out to dinner and/or the bar with a girl (or a few) then a couple of desperate horny dudes.

Just think of what you can have if you don't gamble. I mean, 2 BTC is enough for an all inclusive vacation most places. Also, this might be bad advice, but next time you get money, instead of putting it on a game. Find a girl (that's worth it) and spend the money on her .. you can get a limo, dinner, drinks, show and more for the amount most people are putting on one game. You'll find it much more satisfying.
I wouldn't recommend this all the time, but, hell .. why not at least once ya know.
Agreed re: addictive personality. Since I've stopped gambling for the most part, I've gotten addicted, basically, to exercise. I have the best body I've ever had, and I've run marathons too (from only being able to do a few miles in the past). You CAN get a high from exercise (or other hobbies) you just need to get off the gambling high first. Give away access to money if you have someone you trust (like a good family member I mean).
