Quitting smoking was probably the most turbulent period of my life and it did rock me to my very core at times having to will myself to just not light one up for another moment at times. I can remember being on the edge several times. Thankfully I somehow found the will power to keep saying NO! Just delaying it for a few minutes. As Doreen said about her plan .... just sticking to your self commitment not to smoke again no matter what ...... that's really all quitting boils down to. I really does get easier over time as well - that's not BS. It just happens very, very slowly. So slow you don't really notice it day to day.
Yes, the sleepless nights, the anxiousness, anger and frustration and other symptoms certainly don't help at all and neither does the fact that time seems to be standing still in those early days but it's all part of the quit process. Grit your teeth and power through those early days. Once through, those hellish days will never return
