How will my body react when I quit smoking cold turkey?

My smoking is pretty bad. I started in 2004 @ age 19 as a social smoker, now I’m hitting 2 packs a day.

When I quit I want to go to sleep for 8-9 hours so that my body will have a head start on getting it out of my system. BUT, I dread how my body will react. Any idea of what it’ll be like?

How can I quit smoking without expensive pills/patches?

I have been smoking for 4 years and 8 months so far. I have been wanting to quit for the past few months now, and going to turkey just will not do it for me. I am thinking I just need a stimulant to use to overcome this addiction.

I was thinking about coffee? Would that be enough stimulant for me to quit smoking? Please provide your input!
