Thought I should mention- I'm two days pull free.  I won't say it's the NAC helping... it's probably a little too soon for that.  But with it being Trichotillomania Awareness Week and just starting the NAC- I have been trying really hard not to pull.  So it's been a lot of will power I guess.  Hopefully it'll get easier.  The longest I've been pull free is a week... so hopefully I can make it even further this time!
