If you dont already have one, get a feeding pump. This way while he sleeps the pump can run slowly getting all of the necessary nutrition he needs. If you use the pump make sure to prop him up in bed while the pump runs. Part of the reason your husband has trouble keeping down the formula could be the speed that it goes in. I can not do the gravity or push methods of feeding or I will puke. The only way I am able to get the formula in is thru the feeding pump. Usually nausea can be solved when using feeding formulas either by slowing down the feeding rate or by adding water. Of course nausea caused by chemo is in a class by itself where only strong anti-nausea meds will help that.

My nutritionist has told me to add fiber to my canned formula. Its easily found in any grocery store or drug store. I get the green jar of benefiber or citrucel. This is one thing where I do not follow their directions. It says to use up to 3 rounded tablespoons per day. In my own opinion, the directions are for normal people who do eat other fiber in their diets thru out the day. I add 4 or 5 tablespoons to my formula and shake the bag up real good. Then I let the pump run while I sleep.

Hope these tips help!
