I was addicted for a while too (this is not my first username) but I think I was that way because I was trying to figure things out about my life and mental health. Now that I have--I try to just post and look in the morning. I also made it part of my routine not to use my computer very much in the afternoon and especially during the evening. Maybe force yourself to do other things (work, errands, walks, cleaning, movies, etc.) that get you away from the computer for a while everyday?
