Y'all ask about RU. I went there for about 22 months. While I can't personally speak to the financial cost, they were founded as a reaction against AA-type programs. On the surface, RU points at addictions, but then they go deeper, to the spiritual need. Whether the problem is drink, drugs, or something else, it is not talked about - only the student's relationship to Christ.
The local chapters meet on Friday nights because that is the only time someone in bondage has any money in his pocket. It is extremely liberating to wake up on Saturday morning with 100% of your paycheck in your own pocket. Because of that, other evenings are not as successful.
Their success rate six months out of the program is over 80%. AA has a success rate on day of completion of around 9%. I think numbers should count for something here. Would I do it again? Probably not for myself, but I would definitely recommend the program for others.
