There is someone on CureZone (this forum?) who went to her doctor in Denver -- a good chiropractor -- and he fixed her TMJ in two sessions. If you're going to do chiropractic work, you should make sure you find someone who's good as you can have ill effects from going to a chiropractor if the person does not know what he/she is doing.
Who are these "professionals" you speak of?
Also, it is possible to recover one's health enough to go off of drugs and to counter the effects of withdrawal. Perhaps this is not true for everyone -- for example, if you have been on drugs many years -- but for many I would say it is and furthermore, miracles happen. The human body can do amazing things.
