Speaking only for me, and as someone who, prior to banding, probably vomited a total of 4 times in my entire 50+ years...being stuck isn't that bad.
Don't get me wrong; it hurts, it CAN hurt a lot. BUT at least it's a clear, easily understood signal to SLOW DOWN, CHEW, QUIT EATING!
Yes, sometimes I need the bop to my head! And, it isn't like normal vomiting. There's no bile involved. Usually, too, once the offending bolus of food becomes "unstuck" the
pain is instantly gone. (not always, but usually)
IF you chew well, small bites, eat slowly, odds of getting stuck diminish. It isn't worth not getting the band over. At least, not to me.
You follow your doc's rules, you do the best you can. I can say at 13 months I've NEVER been stuck in a restaurant, never needed to vomit in
public, etc. And the Papaya enzymes REALLY work for me. ANY time it happens it is because I ate too fast, too large a bite (my normal bite is about 1/2 to 2/3 of what I used to do) or didn't chew well. No more eating like someone is going to take it from you!
For me, it's a small price to pay for all the band brings me. Some people do have lots of trouble but generally if you aren't too restricted (just to the green zone or sweet spot) and follow the mechanical rules of chewing etc, you'll be good!
