i wanted the lap band (and was not comfortable with the bypass as once they cut your stomach, there is no going back). even when the dr suggested the bypass for me, i stuck w/my guns and went with what my (head/heart told me). he also did the plication with my band (which is similar to the sleeve w/no cutting) and i am very pleased with my results so far. down 40 since June.
research, ask questions and then ask so more but choose what is right for you. all people are different. i may not lose as fast as joe blowfish but i am loosing at my pace (and slower weight loss could mean.. less saggy skin as can happen w/the bypass).
you are the one who has to do this, so only you can decide.
do not compare what someone else has done. ..that is them... this is you.
all the best GF.
