I had a thirty year nightmare with smoking. I was shunned three times as a result. I reckon the biggest problem was some weird compulsion linked to the taboo nature of smoking in the "troof". I sincerely tried all the approved ways of freeing my self from the habit and the guilt I felt.
Then I got some CBT from the Doc and was able to completly leave it behind. I hated the constant deception and schoolboy secrecy it involved and the risk to health it represented.
I remember the WT article coming out in '73 and the cold shiver it gave me. I think I was destined to have a problem with it as soon as that self righteous crap was released. I think my freedom from the habit came as I discarded the power of all the false junk I had been subjected to for all those years. Ironically as I freed myself of residual belief so the power of the addiction faded.
I am pleased to be free from addiction to smoking now but if there was a good reason to start again it iwould be because the WT banned it.
