Serenidad, you can do this!
It sounds like you have turned the corner in your own mind. That is what this will take... for you to be 100% committed and no matter what life throws at you, you WILL NOT drink.
You can do this, you have a strong will that will get stronger with sober time under your belt.
Like Freeowl said, fill your spare time with something constructive. Idle time is when we think about drinking during the early days.
I also kept a calendar of my sober days. I know some people don't like to count the days, but it helped me early on to be able to physically mark each day off in the morning. It helped build my confidence.
You can do this, lean on SR as often as you can. We are here for you!
