When im eating, after a few bites it feels like I can't swallow anymore and I have to drink a lot of water until it feels like a blockage is cleared?

Stricture. You have a blockage in your esophagus. You need to see a doctor soon to figure out why. It could swelling, spasm, scarring or a growth.
Dry Mouth. Dry mouth will cause this condition. Do you take antidiuretic medications or other medicines that dry you out? Talk to your physician and/or dentist.
