Welcome back, I've done it too Lone so your not alone. I relapsed multiple times after a good stint of sober time.
What I've learned and I can only speak for myself; is that sobriety has to come 1st before anything else, my job, my family, friends ect. I have to be on guard each and everyday and I do that by coming on here each morning and making my commitment on the 24hr thread just for today. For me, I also can't let up on my recovery plan which includes going to meeting every week and talking with my sponsor. I always have to be ready for that time when my brain will tell me " Hey your doing well, one drink wont hurt" My brain & thinking is my worst enemy when it comes to that 1st drink, I have no defense against it unless I do these things.
Just my thoughts.
Glad your back on track
