I went from January 9th this year until July 22nd this year, not by choice.
Medical, and infrequently I would smoke 3,5g/day. Most times ,5 to 1,5g. Typically I would have smoked every evening weeknights and all day weekends. Use goes down in the summer month, and increases fall, winter and spring.
Very bad sleep disturbances that started immediately. I went from sleeping 4 hours straight at night down to no more than 2 hours at a time. That persisted until the day I restarted (194 days). I'm almost back to 4 hours straight after 10 1/2 days of smoking 2-3 times per day.
Within 3 weeks pf stopping in January, I noticed I had lost an unusual amount of weight (not severe, just statistically unusual for me). My overall food consumption has gone all over the map. Some days I eat lots, other days nothing more than coffee, diet coke. When I was hungry, I wouldn't pig out like before. I mean, I understand the munchies, but this was affecting my normal eating as well. No real difference in eating behavior when I started smoking again, but now I find I'm not getting the munchies or cottonmouth (yet).
My mood had worsened considerably by the end of January, and I had stopped taking my dogs for walks (thank God they have a big back yard). I was getting snippy with some people at work (they deserved it in my opinion) and overall just feeling very angry. 12 hours after smoking on the 22nd July it was like a switch had been flipped.
Joint immobility worsened almost weekly it seemed. The arthritis was definitely a bitch during this period. It has slowly improved.
So yeah, basically feeling like shit when I'm not smoking. Having a reduced quality of life.
