Distraction, as above posts suggest, is definitely key - for me, it's things like reading (I adore cooking magazines) in the bath or going to my fave Barnes & Noble, or taking a nap/going to bed early, or making to-do lists, or texting with a friend I know will be around to have a "conversation"...
One thing no one has suggested is drugs - if you have a doctor with whom you can work, and decide if anti-craving/impulse control meds might be appropriate for you, maybe this is something to consider. Other threads have discussed drugs like naltrexone, etc, so perhaps do some research into your options; insurance/cost is likely a factor in taking these, so consider your options regarding that too. These drugs can be good "short term" options that are a big help for some people.
Good luck!
