i have a bowl or two every few days... in all honesty, i smoke whenever i feel like it, but i dont feel like it every day...
i have smoked cigarettes for 17 years and pipes for around 5, and i have been trying to quit.. havent had a cig for about 2 weeks, and havent felt like smoking... in saying that, who knows if i wont feel like one tomorrow.
at the end of the day, i try to smoke only when i know ill really enjoy it these days.
that way its really special and my pipes are always clean, dry and rested.
