I agree with Fnord. You need to find ways to keep yourself occupied. Here are some to try:
- Music--listen and/or play
- Exercise
- Hobbies
- Clubs/activities
- Volunteer/charity work
- Surf the I-net
- Read
- Take courses--either in person or online
You also need to talk to your doctor about help with this. You probably need a higher dose of anxiety med while dealing with the withdrawal symptoms, and perhaps you also need an anti depressant, too.
My mother was addicted to cigarettes for over 50 years. After her first heart attack the doctors kept her in the hospital about a week longer than they usually do, because they had her on strong meds to deal with the withdrawal symptoms, while she recovered from her angioplasty. My older brother had taken her to the hospital, and he took away all the cigarettes in her purse. I got rid of the ones at home, and returned an unopened carton to the store after I found the receipt. My mother was no longer driving, so she couldn't go out to buy more, and none of us would get them for her. So, between us and the doctors, we were able to help my mother through the worst of the withdrawals while she healed from her heart attack. It bought her ten more years before the damage that the cigarettes had already done, finally finished her off.
On the funny side, my mother became addicted to Wrigley's spearmint gum after coming home from the hospital, as a means of dealing with the by then lessened withdrawal symptoms. I know it's bad for the teeth, but it's still a lot better than cigarettes. Perhaps you should try gum to help you deal with your withdrawal symptoms, but stay away from the sugar free ones. I've heard bad things about all of the sugar substitutes being toxic. Just buy the ones with sugar and brush your teeth after meals.
