To change a habit you need to break it. In order to do that you will need to stop drinking alcohol altogether for at least three months. When I say altogether, I don’t mean that you can still drink alcohol on Saturday nights, or if you get invited to a party, I mean don’t drink ANY alcohol for three months.
Sounds like a major task? Don’t let alcohol beat you. You are better than that! Instead of thinking it as a negative experience, see it as a chance to clear out your system and perhaps for the first time in your life see how well you can actually deal with things without the need for a crutch or a drug!!
Make that date in your diary and go for it.
