Or just bake a pie with some antabase in it. that should sort you out.
I couldn't stop noticing that you were trying to make fun out of some serious stuff.
The pie-method is very useful for all people - addiction or not. Some people are not working to their full potential because they have too many displacement activities, the pie-method will reveal that. But you have to be honest when you draw the pie.
Do you have the courage to draw the pie for your life?
My understanding of the original post is that this person truly wants to make a change in his or her life. While there could be a need for a therapist no in-patient treatment is needed. I would support Rotsne and claim that there could be need for an outside-the-stressful-world treatment.
I have just been visited by a man, who quit 20 years of use of a special toccaco some imported to him from the Neatherland. It made him hear some voices and frankly I have to say that his life was very much the same during these year living in a one-room apartment, having only short relationships and having several jobs for short time when not on sick-leave.
He quit it as well as coffee for reasons not known for me. He has been clean for more than a year. With some success he substituted the toccaco use with long rides on his bike and visiting family and friends (Something he rarely did more than 2 times per year. Most of the time he just lived in his apartment partly angry of the world for not coming to him).
When he made the decision it was quiet easy for him because he already was isolated in his apartment. Some who can maintain an addiction and be around people would see the detox process to be a little more difficult. They have to leave their home and put some distance to their normal life.
We have parts of Denmark, we call "the rotten banana". It is parts of Denmark where there is no development and they are converting asphalt road to dirt roads because none use them. Here people can rent a room for several days for under 100 dollars. Do you have have such places in the states where you can get a motel room for a few bucks? Then go there and rent a room while you detox.
Instead of making fun, you should praise him. He has the courage to decide that it is time for a change in his life. What about you?
