I would turn it around and ask you what it is that you think you need the most help with Serenidad. You've spent a lot of time contemplating why other methods are NOT working for you, try and think about why that is. What situations in your life are the most problematic when it comes to staying sober? What are the major issues you have in dealing with life in general?
SR is really only what you make of it, just like any other recovery program. There are forums here for those with many different types of addiction and even for those with mental health issues. Do you feel that you might have any underlying issues that need to be treated by a counselor? I know I did.
So really ask yourself what YOU need to do.
