[quote=walknlite] I have just been letting it for through the syringe using gravity and it doesn't take 5 minutes. [/quote]

Everybody is different, this is the method I used all the way thru and I was doing 4 cans of "formula" plus 8 oz of water or Gatorade for each "meal" 3 times a day.

So I guess to properly answer your question, whatever is comfortable for you, and if one way doesn't work well, that ask your docs about another alternative. The goal is still calories, calories, calories and the more Protein the better !
