No, I did not question myself regarding getting banded. And I haven't questioned my decision since being banded. I feel better about myself, my life, and my future than I ever have. Simply put, it was the best thing I have ever done.
Regarding exercise...I love it and I exercise regularly. But, the band didn't motivate me to exercise, my desire to be healthy did that. Not just regular healthy, optimally healthy.
Certainly, I wouldn't have lost 130lbs if I hadn't (to quote Jachut) "Shut my Gob and Move(d) My Ass". IMOP, losing weight was the bare minimum that I could do to improve my health, not the only thing. But then, Ive always been a "Go Hard or Go Home" kinda person.
