I must
" I will stop and I must stop are two different things when you say you will stop gambling is like you didn't say it whole heatedly, but when you say I must stop gambling, it comes with a strong commitment that you must abide to it, and this will help you to stop it totally. But if you haven't made a serious decision you might never quite gambling totally.
