If I do smoke a pipe in the evening it's usually very late, 12:00am so by the time I come in from the shop it's 1:00am or later. By the time I crawl into bed it's 1:30 or 2:00 in the morning so after the long day it doesn't take me long to fall a sleep. Not sure if it's because I'm dead tired or if it's the tobacco. The pipe certainly makes me more relaxed though.
