It is not easy to overcome an addiction, so here are some tips to help you out with it.
First of all, if you are trying to help alcoholics, then you should do so by first getting yourself the proper help. This means going to an organization called Al-anon and attending one of their meetings. Many people are hesitant to do so and they may not see how this will directly help the struggling alcoholic in their life. And they may be right to an extent, this might not directly help anyone to sober, not right away anyway. But your own behavior and how you deal with an alcoholic can definitely have an impact on their path to surrender. If you continue to enable someone, then they might not be moving any closer to making a decision. You can learn more about this in Al-anon, so it is an excellent suggestion that you get to one of their meetings and share openly with the people there.
Some more tips for recovery would include the fact that you need to take extreme action in early recovery in order to be successful. Most people who are trying to get clean and sober do not realize the level of dedication that they need to taking real action in early recovery. They overestimate their own ability to change and they do not see how much work will be involved in making a huge change in themselves. This makes it very likely for them to relapse and so the vast majority of people end up doing just that. In order to avoid this fate, you have to dedicate your entire life and all of your available energy to recovery, at least for the first year or so at the bare minimum. Real lasting change takes time and so you need to work hard in order to lock in a new pattern of living.
