Yes, it's easier to get clean and sober than it is to 'stay' that way. While using, our thought patterns and behaviors were unhealthy and impractical. Staying clean and sober requires a lot of work on ourselves as human beings: members of our families and of society in general. It's hard work to rearrange those old ways of dealing with life, but it's so worth it. Give yourself time and call on all the support you can muster. We are here for you, as are those in AA/NA. It is in helping others stay clean and sober that helps us stay clean and sober ourselves.
Do'nt be afraid to ask for help and support, for it is in giving that we receive. The only way we can keep the lessons we've learned is by giving them away to others.
