For a moment I mis-read, I thought you put cell wall - which may explained why you have an addiction of unhealthy consequence
I like its nicotine buzz and for that reason I smoke a few times a day. But day buzzes are light. Morning buzz is very heavy. In the morning I get so great buzz that I can't even read the secreen of the cell phone. I can hardly walk or talk. But it lasts short.
At that rate, short is the key word when it comes to your lifetime - however = your choice, and helps keep the Tax down on the things that I and others enjoy - Cheers
