I quit smoking since 25 days some time I get temptation what should I do to avoid?

Smoking. One day at a time. You are in a very good position. You know you have done it for 25 days. One more day and then one more. Candy, gum ECT might help.
Avoid. Have you tried the nicotine patch or gum? There are prescription medicines that can also help to reduce/ eliminate the craving. Also consider what brings about the craving- is it a particular time of day, is it stress? Try to avoid , if possible, the situations which increase the cravings.
