It is true what you say about certain habits that if we are not careful can turn into addictions. For me, drinking a little beer helps me feel good, and if I have one, two or three from time to time, everything is fine. But I'm also not 25 years old, and I've noticed that if I go over those amounts, I get a headache and I don't feel so good anymore. On the other hand, that you are making all these changes for your daughter and for not giving your ex-partner arguments to use against you, is perfectly understandable, laudable and reasonable. I congratulate you for your willpower and intelligence.
