My mom has went from a 148 to 115 since Oct. She got the Peg 2 weeks ago and is suppose to be up to 5 cans a day! I've only been able to get 3 cans down in a day. She tells me she is full and doesn't want to have anymore. She hasn't even started treatment or had her teeth pulled yet. She likes the soup from Quizmo's but she can't eat much of it and it's no calories anyway. How can I get 5 cans a day down that tube?
