As others have said, it could be a form of self harm. What's your end goal? To just feel better? Or to do yourself harm? I had a bad habit of taking too many pills, Advil - I would take eight or ten at a time. My unconscious goal was to damage my kidneys and hopefully die but I wasn't attempting suicide. Any time I feel I am sliding back into the habit I get rid of all the pills in the house or at least put them out of my immediate access.

Definitely tell your Pdoc. You can't move past it if you're not honest. As long as you're not an immediate danger you will not be put ip against your will.
