Thank you allPrimes! I appreciate the info! I am not one to shy away from the testing. I would dislike paying for a test I did not need.....I hope that I am as fortunate as you were!
Start whatever testing you can get on as soon as possible. Options for alcohol are ETG or PEth. ETG is typically a urine screen although it can also utilize hair, nail, or blood as matrices for various lookback periods. PEth is typical blood, but can also utilize hair and nail matrices. If you do PEth blood tests make sure they don't swab you with alcohol of any kind during the blood draw.
Prove undeniably that you're not using and that you're committed to do so ongoing. Stop worrying about timelines and calendars, and resign yourself to the fact that the world operates at it's own speed, and if you do things right you'll be rewarded. Acceptance that you're not in control is a liberating thing. This isn't a sprint, it's a marathon.
You need to demonstrate both chemical abstinence and mental recovery. These are 2 very different things. Once you engage in a recovery program for a period of time you'll get what I'm saying. What gets most people in recovery is that they believe not drinking is enough. It's not. What the FAA wants to see is that you understand the underlying causes of your dysfunctional alcohol consumption and that you're addressing them.
AA/12-step is the "easiest" path in that it's the one preferred by the FAA. That said, the religious aspect means they cannot mandate it due to various court rulings. There are other options such as SMART Recovery which is CBT based. It will never be acknowledged that non-AA programs are frowned upon by the agency, but understand that it is. Most importantly, do what's right to be healthy.
I've seen A LOT of people try to work through addiction. My personal experience is that people who fight AA fall into 2 camps. 1. Genuinely non-religious and interested in a more science based approach (I fall into this). 2. Just generally anti-authoritarian and unwilling to accept help. I'll leave the introspective exercise to you. I'm not trying to sway you either way. Again, do what's right for your health.
One of the most unexpected realizations I've had, is that people who get to true recovery (vs just abstinence) tend to exhibit the same behaviors and actions whether they reach the goal via 12 step or more modern clinical/scientific programs. I liken it to "religious" people and "science" people reaching understanding of one another through belief that the bible and the physics text can tell the same story but do so with different words.
The right "program" is the one that works.
