I've been there. The thing I fine that helps is just doing anything to disrupt the pattern. Go get your motorcycle license, join a gym, get a new wardrobe, paint your room, read a book, anything. If you can force yourself to do something other than what you're doing just once, it'll be easier to do something else the second, third, forth, etc. time.

I find the more disruptive that first change is, the easier the rest become.

Hope this helps.
