You are doing great. I've have traveled the same road you are going down. I started using snuff when I was about 12 or 13 and stopped when I was 37. I stopped cold turkey, after I made up my mind. I can only talk from my experience. For me it was not only a struggle the first few hours, days, weeks or months. It was a struggle for many month's. I did "slip" from time to time, please do not ever give up. It took all the determination, praying and a 12 year old daughter (and a nagging/loving wife) pestering (reminding me) every day to make it through. I would suggest you tell those close to you what you are trying to do and have them remind you every day. This may get annoying and you will be on edge at times so be careful. It takes a lot to do what you are doing - it is worth it in the end. Not only do you save $$ you also save your life.
I will be praying for you and the strength that you will need.
Take Care and God Bless
