Many here has suggested taking a break. But, being in the throws of an addiction it might be a tough withdrawal 
Don't play everyday. Take your breaks throughout the week. My example is that I don't play pool on Monday or Wednesdays at all. I usually play a weekly tournament on Tuesday, league on Thursday, and sometimes a Friday tournament if I don't have plans to do something else. The weekends are for bigger tournaments or if I don't feel like playing then I don't. That's the nice thing about tournaments. You are not obligated to play at all.
As far as practice, you want to keep it short (30 to 60 min) and focused (weak areas). This will also help keep you balanced. Don't get burned out! It's a great game but like Sean said keep it balanced. Good Luck!
