I make a choice every day not to use, they I do it again the next day. I know that sounds overly simple, but that's worked for me for about 8 months now. It is just not what I do anymore. Some day's suck more than others, but, overall I know my life is getting better.
Just remember that you are now 100% there for your kids. My addiction took me away from my son for the last 5 years. Sad. I chose drugs over him. Really sad. I can never get that time back, but I can make sure I don't lose anymore time with him. That's how I do it. Take care.
