I have not tried a 14 FR. My 20 fr allows for pureed soups and supplements. My nutritionist is not a fan of jevity/isosource so most of my survival is based on supplements - liquids, capsules opened, pills ground, and even melted coconut oil. I had a beer about 2 months ago and the foam was funny. Until I am able to swallow there will not be any fun with the tube. I am focused on healing and consume nutrition for healing and not much else. It helps me deal to have a target of swallowing. Wish me luck with the next throat opening procedure.
