First, know why you want to quit smoking. This enables you to fall back on those reasons when the cravings get difficult or the barriers seem overwhelming.
Second, be persistent. The withdrawal symptoms usually peak in the first 3 - 7 days after quitting and taper off over the next 3 - 4 weeks. So expect to be angry and anxious for a while.
Third, review treatment options with your doctor. Studies show that having a physician follow up with you can double your success rate.
Fourth, change it all up. Keeping the same habits can trigger the smoking response and sabotage your efforts. Pick up a hobby or exercise, anything to change your normal routine.
Fifth, develop or enroll in a support group of people who can be there for you when times get tough. There are on-line forums that may provide you with that extra little help. This also creates an accountability network for you.
Next, throw all the left over cigarettes, ashtrays, lighters, etc. away. But not in your trash can, as many have been known to dig them out of the rubbish. Instead, bag it all up and toss it in someone else's trash.
Finally, keep these and other tips handy.
