I consider addiction to be permanent just from my interactions with people in recovery and people who have relapsed with significant clean time. they always say it was way worse and was not like being naive again. which implies some kind of progression in severity regardless of how long a break this person had from using. those with the most clean time before relapsing seemed to cause a lot more havoc as if making up for lost time. most clean time I've had before relapsing was around 6 months and the fiendish behavior for me was a lot worse than at the beginning which implies my addiction still progressed on a sense.
What I have found is that every relapse is worse than the one before. You hit rock bottom faster than ever & every rock bottom has a trapdoor to fall through. It is also worse when you have sobriety time because you know the end result before you even start as well as knowing you are betraying yourself. The mental side is the hardest to recover from after a damaging run I have found.
I subscribe to "addiction is a lifetime deal" scenario. I will always be an addict until the day I die regardless of how long I have sober & I accept that. Addiction is a choice no two ways about it.
I have two choices in life,
Abstinence: Making a conscious choice to not engage in activity that is detrimental to me.
Activity: Making a conscious choice to pick up
Once the choice to go active is made there is no off switch for me. Therefore my only choice is to be inactive of active as once active I am powerless over what will happen due to my addict mindset. With me it is as quick as turning a light switch that is how fast I slip from abstinence to activity.
A good friend described it as "your addiction is doing pushups & getting fit as fuck so that when you slip it is ready to do catastrophic damage in a short timeframe". I could not agree more as the addiction is there waiting for you to allow it to re enter your life & it only needs the slightest fingertip hold to break the recovery door wide open.
Thoughts of picking up turn to obsession. Obsession leads to action & action leads to prison, insanity or death. I am not a regular 12 stepper these days but the basic principals are applied in my daily life. The most important thing is to
use what works for you & in early recovery you have two ears & one mouth so use that in proportion. Learn & listen to those who walked the path previously, take what works for you & use it to your advantage.
