Nate, I know you have a feeding tube. Sorry for giving you the shake recipe when it might be something you are unable to have right now. Keep it for down the road when you are able to drink again.
It would be a good idea to go thru the green Amazon box on the main forum pages to buy a case of Carnation VHC. Depending upon which formula you are using, you may want to add a couple cans of C-VHC. That has 560 calories per can while formulas are usually 175, 375 or a very few are 560 calories. Formula can be very expensive. I was charged $80 co-pay per case which was supposedly discounted from $220 per case. C-VHC is about $48 per case thru Amazon.
Here is a link to Nestle website. Write them a letter and ask for them to donate cases of formula to you. They will send you a form to get filled out by your nutritionist or doctor. Just make sure they fill out every single thing, if one item is missed they throw your application away. I know cuz they sent me 12 cases of formula for free.

Make sure you do this in advance since it can take about 2 weeks to receive anything. All you need to do is pay for S&H by sending a money order to the person who has the supplies you want. You can either call the 800 number or email them and get a list of people who have the item you are looking for.
