Bad habits can be difficult to get rid of. It is even more difficult to motivate someone close to them to refuse them, given that secondhand smoke, for example, harms not only the smoker himself.
If a person is addicted
If one of your friends or family members is excessive in alcohol or cigarettes, you, of course, can worry about him and wish him to take more care of his health. This desire can be especially strong if his bad habits are giving you trouble - forcing you to inhale smoke, endure inappropriate drunken behavior, or take on responsibilities that the person has ceased to cope with due to his addiction.
Unfortunately, no one can be forced to change anything in their life, unless the person himself wants to. And to give up addiction, you need a very strong motivation. Therefore, if you expected to become a savior for someone, it is better to immediately abandon this venture.
It's another matter if a person sincerely wants to quit drinking or smoking and asked you to support him in this. In this case, you can do your best. For example, you can cheer the person up and praise them for each day they go without a glass. And at the end of each such week, encourage him and yourself - go somewhere, enjoy an exotic dinner, do something pleasant. When a person refuses habitual stimulants, at first he has a withdrawal, albeit a small one, and during this period it is important for him to receive pleasant emotions and hormones of joy from other sources.
If your efforts are successful, great. If a person promises to stop drinking from year to year, but starts all over again, you may be powerless to help him. In this case, he should seek help from a specialist. Sometimes wives cannot leave their alcoholic husbands out of pity or a sense of duty. Although, you also need to take care of yourself and it is worth considering and deciding whether it is time to leave the relationship in which you are playing the role of a victim or an unfortunate savior. Maybe it is the threat of losing you that will finally force a person to show willpower and take care of himself, but if not, then the situation is hopeless.
If you are for a healthy lifestyle
Perhaps your loved one is not addicted in the literal sense of the word, he just occasionally smokes or drinks alcohol, like most of the population. But you are leading a healthy lifestyle and want him to follow your example. Here again, everything depends on the desire of the person himself. If everything suits him and he does not understand why he should give up these benefits of civilization, he will simply look at you as an annoying school teacher trying to read him morality. The only thing you can do is tell more about the dangers of cigarettes or alcohol and hope that the person will be absorbed, or leave him alone, and, perhaps, after a while he himself will want to follow your example.
If you categorically do not tolerate alcohol and smoking for reasons of health or morality, and your loved one cannot imagine an evening without a bottle of beer and smokes two packs of cigarettes a day, maybe you are simply too different people and will be happy next to someone else …
It happens that a couple plans to have a child, one of the partners considers it necessary to give up bad habits a few months before conception, and the other does not see the point in this. If this is your case, you, as one of the potential parents, have the right to ask your partner to stop drinking and smoking. If he refuses, say that then you stop trying to conceive and postpone this goal indefinitely. If health and family are important to a partner, they are more likely to compromise.
