I'm 7 days into it, so baby steps. I'm certainly not an expert on AVRT, but seem to have used it when I quit drinking 18 months ago.
Of course, I was prepared for the counter attack that got me last time I quit smoking: panic attacks during my sleep/waking up every 5 minutes feeling I'm suffocating.
I don't think that's something that you do to sabotage yourself, and it really freaked me out last time around (about 4 years ago). This time I was prepared, and since last night it's starting to get less bad.
I honestly don't even know if that is my AV, or just my body/brain freaking out after having smoked for 40 years 3 to 4 packs a day. However, I did treat it like it was my AV, monitored my BP to be sure (nothing wrong there apparently), and stubbornly followed my plan of never smoking again.
