Nicotine itself is unlikely to reduce stress. Taking the break, doing the habitual ritual, feeling the effect hit you is what gives you time to settle your mind. Find something else that mimics the same ritual awareness. Flip a coin five times, do Rika's push ups, whistle a tune - whatever is appropriate to the place and situation.

With time you will realize that smoking doesn't make you feel good - it stops you from feeling bad. Once out of your system, cravings gone and 'rehabituated' you will have a happier baseline to work from.

Congratuations and good luck!
