My whole family quit today!!!

You will all have to forgive me as it has been over 18 hrs since my last cig, and I am finding myself to be in a rather thick fog. Anyway I am searching for help for not only myself but my entire family. All six of us adults have decided to quit cold turkey. Both of my brothers,quit smoking, My mom, my sister-in-law, Myself and my fiance. I suppose I should explain how we all came to this decision. Its quite simple actually my mom has been diagnosed with emfazema ( sorry yesterday I could have spelled it right but I am drawing a compleate blank today) And yesterday she had to go to the E.R because she was having problems breathing. The doctor told her that if she didnt quit smoking she was going to be put on oxygen soon. So while she was in the hospital we all decided that the only way she was going to be able to quit was if we all quit too. And we knew it would help to motivate her if she could get all of her children to quit. So we made her a deal you quit we quit. My mom has been smoking for over 35 yrs ( 1-2ppd or packs per day), my oldest brother over 25 yrs (2-3 ppd ), my other brother 22yrs(2-4 ppd), my sister-in-law 2 yrs(1 ppd), my fiance 7 yrs(1-2 ppd), and I have been smoking for a little over 4 years(1-1.5 ppd). And not ONE of us has had a single drag today!!! However my younger brother and fiance have succumbed to the temptation of chew (GROSS). But the rest of us are still going strong. Strangely enough my oldest brother (smoking for over 25 years) seems to be doing the best. And even though I have only been smoking for 4 years I am finding myself in a thick depressing fog. I really dont feel like myself at all. I am thinking about joining the ranks of my younger brother and fiance and buying some of that new no spit chew. And on top of everything I am scared to death of gaining weight, as I am getting married oct. 25th. So not only am I quitting smoking but I am also planning a wedding and trying to lose a few pounds so as to fit my dress!!!!!!! Any advice, tips,smoking cessation, trics etc... you all could give would be greatly appreciated. Thanks muchDaisy
