Ron had that tube twice and pulled it out himself twice! Not what I wanted for him to do. But it bothered his nose it was sewn to the inside of his nose and the 2nd time he told them to cut that thing right now! He hated that it was attached to his inside nostril! He used to loop it over his ear when he didn't use it and it would dangle like an ear ring. Never had any problems with his stomach but he complained bout the irritation in his throat from it that's why he pulled it out. I think only very thin liquids will go thru not any kind of food blended but we never tried it but it is a little tube.
