Bill,
I still remember you playing guitar behind me at one of Don's jams. You were telling me the chord changes. That was a fun jam.
Now on to the subject, the jury is still out on DC. You might want to check out quackwatch.com. They have their view of Chiro and you can tell by the website name it is not favorable. Other people swear by them. I guess it is results that count. If you are getting better and feel it is because of the treatments then by all means continue. My own personal opinion is that Chiro is of limited benefit but sometimes helps. I would get an MD's second opinion if it were me.
Don owes you big time, make him pay!

Tom
