Does your doc have a Lap band restriction guide "aka the zones" anywhere in his exam room? It talks about being in the yellow zone not enough Fluid and what that feels like, green sone and red zone?
Yellow is where you are not loosing, not having staiety with your meals "hungry all the time"
Green: this is where you want to stay for good wt. loss. proper satisfaction with a small amount of food. can go several hours 3-4 hrs. w/o hunger no sticking or reguritation, heartburn. and good steady wt. loss
Red: this is where you should never be or if you do find yourself here get to your surgon for unfill.
Poor food choices(sliders softs, things that go easily thru the band) Can't eat without pain things won't stay down(you throwing up or productive burp alot) or you just plain out get stuck and have to vomit.
Some folks get shoulder pain in the left shoulder when they are to tight.
hope this helps.
