Keep posting...do you have someone to talk to? I have had a couple urges that I did not think I could get through but hearing the absurdity of what I was saying to my sponsor or my father seems to help get me off the ledge each time. Maybe hit the gym or do a yoga class too (not sure if your into this).
Good luck - if I go back and look at your posts, you have come too far to cave to the AV.
