When telling him about my plan for a month of sobriety, a friend said to me, "Not drinking is EASY. Not playing online poker for a month...that's HARD." I laughed, but I knew he was right. So, I looked it up on the different poker sites that I play on and they do have a policy for self-exclusion. All you have to do is email them and tell them you want to be excluded for (insert time period) and it goes through. You cannot undo it. One site in particular actually has the options right there on the browser along with confirmation and everything.
