I frequent that forum as well, there is a TON of great advice and information there and helped me through my "darkest days."
I think that with every surgery there will be at LEAST 10% indecision or worry, as there should be. The outcomes for each individual can vary greatly, and although lap band is the least invasive of all WLS, there are always risks associated with every procedure.
I hope you find which procedure works for you and it is a HUGE success! As far as eating at Disney, I can still eat whatever I want with the lap band. That is the beauty of the lap band vs. other surgeries (some would consider this a negative, but definitely not me). Is that you can tailor the band in a way that best suits you. My band has very little "fill" (saline) in it so I can avoid the "stuck" episodes, and other restriction problems that come with a bigger filled band. Of course this little fill works great for me, because it lessens my appetite, but still allows me to eat foods that other bandsters have problems with (chicken breast, dense meats, fibers-all the things your body needs). However, it also allows me to eat everything I want. Luckily, I have NO desire or hunger to go back to my old eating habits, but if I want pizza on occasion, I have no problems.
I went on vacation in May and had my band unfilled because I didn't want to "fight" with it (meaning the band is very fickle and can let you eat foods one day, and not the next without issues). I didn't want to be in a position, @ WDW, where I was seeking out specific foods or having a "stuck" episode let's say in line @ Space Mountain
Long story short, I could eat whatever I wanted and in whatever portion I wanted to. Of course I didn't, and kept up my workout, but that is me. MANY people who chose the band WANT severe restriction so that they are physically unable to eat, that is definitely not what I want, EVER! I want the band to help me make the right choices and lead me to a healthy life long term, which is what it does.
This is how I choose to use the band, you may choose differently. That's the beauty of this WLS procedure, it works differently for everyone!
