Congratulations SB! I too gave up alcohol during conceiving and pregnancy, but there is not a glimmer of doubt in my mind that I cannot drink as a normal person. There are many alcoholics who have stayed sober for years and years, but if they were to take a drink then a binge or uncontrollable outcome would be their destiny. I think, for myself, my problem lies with that first drink because it rarely ended with just one and if it did I suffered with the struggle to keep it there.
I feel much freer not having that inner struggle in my life and my mind is freer to consider other thoughts in life too. Much better in my opinion.
As far as whether you are an alcoholic or not does not concern me. Labels do strange things to people and I would go with your list of reasons for now. Congratulations on making your first sober day your son's birthday. What a gift to his Mom and to him. Awesome! Hugs - Sarah
