I am in agreement with everyone else's advice as well.

I had a similar problem, not with any addiction to my computer or my newfound submissiveness but with the fact that I had started to neglect certain routines just because life changes, and by the time I realized it, I had pretty well lost all my daily routines and was becoming dangerously lethargic.

I elicited the help of a Dominant to help me get back into a better lifestyle, it took about a month of constant routine and a lot of punishments.

But don't forget it is also up to you to pull yourself out of your rut before you realize that it is too far late and some permanent damage has been done.
Talk to your Dom and ask him to help guide you into a better routine for yourself. And take some time out each day to daydream, use your computer, watch a movie. But limit yourself with that time.
