Sometimes I get a feeling of something sitting in my throat. This happens even when I only eat 4-6oz. What does this mean? Does this mean I have eaten too much?
You're definitely not eating too much if you're only eating 4-6 ounces at a time!
However, your band may be a little tight, necessitating that you eat even smaller portions, but more frequently. You also may want to avoid laying down/reclining 2-3 hours after eating.
