I have seen many people get huge after drinking from their shower hoses... How does one do this easily? Tips?

Okay, so I just recently figured something similar to this out. First of all, don't start with a full to the brim cup. While preparing take a small breath. Right before the liquid gets to the back of your throat, swallow. And repeat swallowing till gone. It's not perfect but its as close as I got to what you may be trying to do.

Looking for recommendations on food that fills you fast, and tastes good. It would be great if it were also cheap.
