Apollo Overstitch procedure as revision to RNY

Hello,  I am interested in talking to folks who have had the Apollo Overstitch procedure.  I would like to know what your results were.   When  did you have it?   How much weight did you lose?   Did you have to do a lot of dieting along with the procedure to achieve results?  A friend of mine is considering this procedure and I am concerned that it may be just as useless as the Rose, Restore and Stomaphyx procedures that were so hyped up just a few years ago.  It's apparently the same concept, only done with a different type of suture and a newly designed piece of equipment.
