First, don't get disturbed by anything. Once a saint said "at the disturbance the enemy stays and at the peace – God stays". Don't be disturbed even if you can't break your bad habits right now. Just wait for the moment when you will feel an inspiration in your hearth telling you "now is the time to finally be free of this". And act accordingly with no fear. When you have to do something according to God's will, even if it seems difficult at first, it ends with relief (unlike what the devil suggests us to do, which seems very desirable at first but ends miserably).
And by the way, there are other, even more important things, you'll have to change in your life as a Christian. Just have faith that God loves you and be grateful that in proper time you will be given the option to put off your old man, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your mind, and to put on the new self, created after the likeness of God in true righteousness and holiness. (Ephesians 4:22-24)

Unfortunately, the various Christian denominations have very different opinions about the requirements for our salvation.
It is my understanding that according to the Catholicism, our salvation requires proper balance between good and evil. For example, I think the official Catholic catechism speaks only against excessive use of tobacco but not against the use of tobacco in principle.
On the other hand, for the Orthodox your salvation means alignment with God in every aspect (mind, will, wishes, body), no compromises are allowed. This is an infinite goal, so no amount of virtues can make you closer to the heaven. At the same time because of Christ no amount of sins can make you unfit for the heaven. You simply use what you are given for free by God in the Church (grace, advices by your spiritual director, abundant spiritual literature, inspirational examples) and you allow yourself to be transformed into a new man.
