I've only been smoking for about 5 weeks (having never smoked previously), and I've gone through a period of adjustment similar to what has been described here. Not knowing anything about it, or even anyone who smokes, I did a lot of research on the internet about how it is done. YouTube was a great deal of help...except for the dude who lit and ate a cigarette (blech).
Here's what helped me build this new skill:
I read somewhere that, apparently, new smokers often take puffs that are too big to manage, so I found that reducing the amount I inhaled at one time was much more comfortable. This also cuts down on the vertigo, especially if you don't rush through your cigarette. For me, relaxing and taking a drag no more frequently than every 4th breath was much more enjoyable. I also make sure one of those breaths between drags is a fully counted "round breath" from Laura's Eiriu Eolas breathing exercises. Doing the full EE program several times a week is also most beneficial.
After getting several bouts of upset stomach after smoking, I also discovered that I was breathing into my stomach instead of my lungs when I inhaled. As a former runner, I know that inhaling through your mouth does not have to impact your stomach, so I paid attention to how I was inhaling when I smoked. What I noticed was that, since I have something between my lips, I expect to be swallowing it soon and automatically get my tongue, lower jaw and the muscles in my throat ready to swallow instead of to inhale. The solution was to mindfully relax all those things, especially the lower jaw. This, combined with smaller puffs adds more enjoyment.
Smoking has given me significant clarity of thought, energy, relaxation and freedom from the ruminations that lead to depression. Caffeine by itself does not do any of these things, except that for an hour or so, it gives me the energy to natter about nothing. In fact, caffeine causes me to talk without thinking, while smoking helps me think but not necessarily to talk.
I think it's well worth making the effort to find a comfort level with the art of smoking. It's also important to remember that while we are conditioning our bodies to make the physical changes brought about by smoking (increases in acetylcholine and building receptors for this vital neurotransmitter), we are also removing part of the Matrix's programming in our subconsciousness. Removing programs is quite difficult because they are hard to spot in oneself. The anti-smoking one is out in the open, thanks to Laura, so it can be used as a toehold to reach for the next one.
