Query: A stop-gap solution, but for the long term?

If you have an urgent need, this may work like a short-term fix, much like a medical drug. However, I'm uncomfortable doing this for the long term. Many find this method draconian, and not the most easy to do, and the results and benefits still questionable by the experts, who remain divided. Go back to basics, look at alternatives like "This Body This Life" from Asia, which seems like a down-to-earth, honest and practical approach for the long haul. No short cuts, but it works.
