Hi mjs, congratulations on your sober time so far. Hope your doing ok.
It seems to me that whatever you do or don't come to believe, your behavior and your experience is more important. I haven't read the Dawkins book but judging from reviews it does seem to miss some points about religion in its rush to say "its not scientifically true". It's not about whether its 100% true or not, but what belief can inspire people to do. Belief has inspired some awful things (war etc.) but it can be useful and profound too. If Dawkins is right, does that mean we should no longer listen to Bach or John Coltrane? Freud, who coined the term "the future of an illusion" from which Dawkins takes his title, was an atheist, but had a complex and balanced view of religion.
So even if you are going through a crisis of belief, don't dismiss your own experience and knowledge, or think of yourself as foolish or childish. It's not all black and white, in spite of what some might say. Just don't drink or use, one day at a time,
peace, nl
