Thank you. In all likelihood I'll keep it up ;)
For anyone interested, Allen Carr's book was the thing that finally worked to get me stopped, and then later NAC (N-acetyl-cysteine) that I was taking for something unrelated seemed to really make me just forget about them altogether. There's something about NAC and various neurotransmitters that seems to have a positive effect on addictive/compulsive behavior. I had no idea at the time, this was before anyone knew that about NAC, but it seemed to help with the persistent thoughts once I had already quit.
