bob, I have been useing jevity 1.5 for a month. I start out at a 75 setting, 77 when i go to bed and then when I wake up at night to the potty i increase to 87 or more depending on how much is left in the bag. then i pour the left over down the tube so i get the full amount. usualy about 5-7 oz. I have diarea ounce in a while. then I take one imodim and it stops. I also take regalin 30 min. three times a day. it helps move the formula through the digestive tract. Hope this helps. Pat
