Orion,
Rehab can help you detox and stabalize while getting some
basic education about your addiction and one on one
counseling. A halfway house might be a logical next step
if you've been practicing your addiction to the point of losing
your home, family support and/or ability to earn a living.
Structure in your life is important for all of us but especially when first clean and sober. If you have a job and home
then I'd strongly recommend AA or NA meeting Daily to stay sober and get the support you need. AA also helps you learn to deal with life without having to drink or drug. Basically, you have the emotional functioning level of the age your addiction started so the steps of AA and NA help
you develop coping skills so important in handing life.
Best of Wishes,
Annie
