kaamom - i, too, am happy that you've re-thought your decision. since your type of surgery would only last 2-3 years, i think that you've made a wise decision.
if you still *need* it later on, the option is always open for you.. however, i still would never do it.
i've forgotten what type of treatments you've tried... what are your plans now? have you seen a neuromuscular dentist?
take care.. we're here to help you out, at least emotionally.
