Everyone who participates with online casinos/poker rooms needs to understand their own motivations and keep these impulses in check. Kudos for Mr.Van for bringing this topic up. Everyone here needs reminders that there is a real world out there.
If it's games that keeps you playing - check out the "for free" games that IGT and Leading egde designs make available. There are a number of really cool
VP and Slot games here:
If this is the case, book mark these sites:

If it's money you're into, like Spear said - disable your Insta Cash at Neteller.
Another tip, turn off your computer and go take a walk. Get into the real world. If you have a family at home, go play monopoly or some other game where money is involved. You can take care of that "money" fix this way.
If playing online ever affects your relationships or makes a serious dent in your bank account. Stop doing it - period. Thunderstruck or online poker is not worth screwing up your life.

Also, somewhere in the forum - there is a link to a site that offers a service to block all gambling related websites from your computer. If anyone can dig that up, that would be great.
