Sorry to hear that! I know it's not the result you wanted, but it does demonstrate the importance of getting motility information before doing anything to tighten the LES. I hope you find an answer that works for you very soon.
Again, my sincere sympathy that your results weren't what you had hoped. Don't give up...there's an answer out there for you!
