I've had similar problems. After trying to overcome the problem myself for much too long, embarrassed to even reveal it to others, I found a great therapist and they helped immensely. Probably the most important thing I learned is that there are healthy, very human needs behind bad behaviors. Stop fighting yourself and doing tricks and workarounds (hacks, etc.), and start caring about and helping yourself. When you can't focus on work, what do you really need, on an emotional level? What does the video game provide? What are you avoiding? If you don't understand your subconscious drives and emotions, you will be a slave to them.
