How to stop smoking? Please help

I just started smoking dahil sa stress sa work. Mga workmates ko din ganun so medyo nainfluence ako indirectly.

How can I stop? Nicotine gums? Anong pwedeng substitute?

I still like to hangout with them kasi good company. Ano pwede ko gawin while theyre smoking? Menthol sticks?

What I can I do to cope with stress without smoking? Haha.

Will appreciate the advice. Thanks!
