caffeine - may make it worse?

My skin picking seems related to anxiety levels. For the past month i've been doing a trial of no caffeine, and things are much imporved. I'm still popping to the mirror now and again, but less frequently, and spending less time there. I've not gone into a 'trance' state, and i've not been obsessing about lumps and bumps either. I think its a bit of a success - aside from being really sleepy for the first couple of weeks. decaf from now on!
