My Mum had Social Phobia and Depression and that caused her to become an alcoholic from my age 2 up until 8 years.
By this time i had developed seperation anxiety disorder and my social learning skills and development of personality had been seriously damaged.
My Mum asked me at age 7 what I wanted for christmas once and I said "I want you to stop drinking". My Mum cared about me and a year later she stopped a cycle of 13 years (with 2 or so years break from my age -1 to 2).
My Dad was an alcoholic and he didn't care enough to stop because I was just a THING to him. Even if you're not an alcoholic you still have a slight alcohol abuse (daily drinking) and should be careful Worrydoll. If you love your kid you'll eventually decide to stop drinking daily (it has a very negative effect on development of children) for him/her and mainly yourself.
Drug abuse, alcohol abuse is not a solution. I've had a slight substance abuse when I was 16 to 18 and I never want to go back. I hope you don't take offense in what I've said because what matters at the end is what you want. Maybe the reason why I am so against substance abuse now is because I have been at that stage somewhat and I have come out of it. I've lived with 2 parents who had a substance abuse and have experienced that as well for many years.
