The first week is the hardest part....get past it and you are well on your way.
A few things to think about and/or do. Exercise as much as you can and drink alot of water. This will help you burn off alot of stress and get your mind on something else. It will also help you keep you from gaining weight. I worked out every day for an hour when I quit and it really helped.
Try to find something to tame the oral fixation monster. Everyone finds something different. Some use toothpicks, fireballs, mint candy, fake snuff. I found that beef jerky bites worked great for me. They are little chunks of compressed jerky that are about the size of a big dip. You can keep them in your cheek for quite a while and curb the urge.
As for the anger, you just have to try to keep calm and walk away. Exercise will help this too. Remember, if you dont quit there is a good chance you wont be around to bitch out anyone cause your face might fall off.
Make an appointment with your dentist that is about 30 days out. At that point you will want to have someone do a complete check of your mouth and it will relieve alot of anxiety that you will probably have. We all get torn up worrying and getting this done helps out more than you can know at this point. It also gives you a short goal to reach. As stated above you will have days where you are in the "fog" and days of anxiety and depression for no reason at all. It will come and go and is just your brain resetting itself.
Prepare for all kinds of weird things to happen to your mouth. Some get sores, sore throats, bleeding gums, etc. I was lucky and only got a few sores, but did have tongue issues. After about 1 week, my tongue felt like I burned it on hot coffee making it tingle and feel numb at times. I am on day 138 right now and it still comes and goes. It just goes to show you that it takes a long time for your body to get used to not being bathed in poison every day.
When you get the urge, turn it into something else.... Go for a run, drink a glass of water, eat some candy, turn on the radio and sing to yourself.....anything to get past the urge. After a week or so you will find yourself actually forgetting about getting that after dinner dip. It's hard to believe, but it will happen. I have days that I dont think about it at all and I dipped for 25 years.
QUIT ON and be strong!! AND POST EVERY DAY!!!!!
