Okay, if it's getting stuck, you're not producing enough saliva or chewing your foods enough. You probably have a bit of inflammation going on in the esophagus too. oh dear.
Don't do another SWF, give yourself a break.
Definitely go for the veggie broth! you can also eat quinoa easily enough, and see about making some Kichadi.
So sorry the fast did not go well; sounds like you need to jsut do a limited diet for awhile. :)
