If it is not affecting your sex life, and if it is not taking away time you should be spending on other things, and if by thinking about it does not stop you from doing your normal work, then it is fine.

When I'm not using it, I'm thinking about using it. And it's awful. I feel like it's consuming my day.

This seems to indicate that it is creating a problem. Over use of any type of vibratar will reduce your responsiveness to less intense types of stimulation such as a hand or tongue.

You may be better off backing off this thing, using your hand, doing kegels and taking up a good workout program.
