just reread your original email and realised your husband is not even on a high energy drink. Get your dietician to prescribe Ensure Plus. It is not available to the general public and you have to be registered with the company who makes it for you to buy it. Once registered (your dietician should do this), you order a month's supply at time and they deliver to your door. Can't remember the cost but it is cheaper than buying all that food to tempt your husband and MUCH cheaper than Nutrison if you end up with pump feeds. The ensure plus can also be administered through the PEG but do it slowly at the same speed as if your husband were sipping it (avoid bloating and subsequent refusal to take on more). Suggest 50 mLs, wait a few minutes then another 50mLs etc.

This should supplement whatever your husband can take on and can subsitute should he become unable to eat anything. My Alex has 7-9 Ensure Plus's per day and it is his only means of nutrition (number 8 and 9 are a struggle though).
