The key here is to find the underlying problem, professionals can help with this.

If you want to stop then, stop. Make a contract with yourself and then when you break it note it down, and then move on. Soon you will stop, it just takes time.

And finally, you really don't want to know EVERYTHING. Somethings are better to be discovered over time. For one thing, I really don't want to understand why I have to deal with so much. I don't want to understand why some people drive so SLOWLY. I don't want to know the answer to a complicated problem. I want to discover it out for myself in time. I believe the correct term is Self-Discovery. Finding out who you are, and how to fix your problems. If you didn't learn, then you could not understand everything. You have to learn first and then understand. That's just how the world works.

Just try and stop. It will be hard. The urges will still be there. You just have to keep pushing against the urges. I hope this helps, and make sense. (up for tomany hours with out to much sleep) Good luck on stopping!
