Ghost:
You have to want it, accept it and do everything you can to not go backward. Written down it seems to simple, HUH?
You need a plan, whatever the hell that looks like to you. Finding something else to do when you are triggered into booze, sex or drugs.... A hobby.
It seems like you have grouped together a few days here and there throughout, so it is IN YOU! You just have to work for it every single damn day of your life. It will get easier, and it does. The relapses are what makes it much harder with every single relapse.
Look at what you did leading up to your relapse, write that down, the feelings, person, situation, etc... and DO NOT do it again. It appears you were getting romantic with a lady, in this situation I would totally agree with the suggestion in AA: No relationships for a year, work on you so the blinders can be lifted.
Only you can do the work, you know that.
If this is coming out strong, it's because I know you can handle it. You are a straight shooter, no BS kind of guy.
