I was a twenty y/old when I converted to the JW religion and was a problem drinker and I was a chain smoker .When I was baptized at a Circuit Assembly a year later , my conversion and change in lifestyle was given as an example of the effectiveness of incidental witnessing to the audience.
So I can point to the 2 positives becoming a JW .
1.I gave up smoking
2.I gave up drinking for a while ,but because I still had association with my wife`s and my family who were not JW`s ,I learnt to control my social drinking when I started again.
And I have been a responsible drinker ever since ,even though I left the religion 29 years ago.
The negative points of being a JW in my 32 years of being one ? are far too great to list here .
Love to hear your thoughts.
