I was smoking a pack of tabs a day, started when my Dad's health was in decline, and continued for a while after he died. Two years in all. I won't deny they were very relaxing, but I decided to quit because only morons smoke. I was a moron, I knew this and I didn't care. The quitting bit was no bother- I stopped smoking one day and got on with my life without them. I can't say I really had any serious withdrawal issues. The worst bit was realising how much my effing clothes stunk of smoke!
