When it comes to recovering from an addiction, there is not necessarily a right or wrong way to become sober but there are simply choices that can be more effective depending on the person. For people who have been addicted to drugs for a number of years, it would benefit them greatly to attend 6 month rehab so that they will have the maximum amount of time possible to really focus on recovery and put in the necessary work. A really short stay at rehab or trying to rehabilitation yourself alone could lead to more time spent relapsing instead of being on your way to a completely sober life. The kinds of pitfalls that can occur when you do not get the proper kind of rehab can make it harder and harder to ever get out of your addictive behaviors. The key to effective rehabilitation is spending quality time discovering personal issues that are directly related to your addiction. What made your addiction start and what are the triggers that cause you to engage in substance abuse? Understanding these things can help to prevent problems from coming up again in the future.
As you wait for the right time to finally leave your rehab center, you will have to make sure that you are completely ready to take on your normal life without any kind of danger of you experiencing relapse. This will be a combination of the right amount of time for rehab and your own personal feeling of commitment to sobriety. When you are certain that you can survive alone outside of the sober rehab facility then you can find plenty of resources to help you remain sober for many years and even for the rest of your life.
