trichotillomania
"I have pulled my eyelashes and eyebrows since I was 12 years old-am now in my 50s. I recently tried the drug, Contrave (naltrexone and wellbutrin combo) , for weight loss and found that it got rid of my desire to pull. I take the recommended 4 pills/day but don't know how much naltrexone is in each pill. 
I still have the urge to pull as my usual response to anxiety but the ruminations about pulling, what to pull, where to pull have been greatly reduced. When I do pull, the feeling is very different and now feels like what one would expect when ripping out eyelashes (ouch!). I would say that the "feel" of pulling is different-the drug interrupts the pleasure of pulling and I don't feel compelled to pull more. very interesting drug."
