Oh honey!! Please check your Ensure..I think it has sucralose in it and that sent me to the hospital one time.. my "fellow" ( I'm 71 and don't know how to say "boyfriend" .. sounds so silly!! but he has been my neighbor since 1997.. he's is widowed.. his wife passed in a car wreck.. along time ago . and their daughter 8 was in the car and saw her go thru the windshield.. he had to raise 2 girls by himself .. with girlfriends.. anyway..she got on drugs and had a baby .. and some "friends" of hers knocked her in the head and drowned her at age 27..her little girl wasn't there about 7 years ago..now you know something about him,,, if he hadn't been here I'd have surly passed several time ago.BUT..) he drinks BOOST.. no sucralose!! It has whey protein ( milk) and I have to stay away from it as much as possible!! It should help your Vitamin D tho!! And I have to order PLANT based Ensure off Amazon.. sooo... I'll be praying for you!! I'm praying for you and your doggie!! ( I've had so many dogs and cats ..so had to watch them grow older.. had a dog 18 I had to put down and my husband's cat .. 19 ..I know they mean a great deal to you!! Please let me know how the Ensure works for you!! I'll be praying !! I hope you have a great day today..Mother's day.. hope they treat you like a "queen".. because you are!! Hugs and love dear friend!!
