I haven't piped in - I don't think.. I know the break through meds aren't helping much frankly it sounds like nothing is) I was okay with chemo, rads was hard. Though I did have bouts of nausea mostly related to my tube, so I stopped using it after two tries and bit the bullet.. Maybe try getting him to take his meds about 15 minutes prior to eating, have him down a bottle of ensure and either sit up, or lay on his right side to help drain his stomach a little more quickly. I found position made things a little better laying on your left side makes it harder to drain your stomach. Ensure is fast, if you get the one with extra calories it has almost as much protein as the protein plus ensure has! I survived on four to 5 a day, and learned to chug them in 13 gulps!! They are bland - texture free and shouldn't trigger too much gagging (I found the thng that was worse was gagging on my own spit. I kept a cloth nearby, to spit into, and a glass - gross I know - I also rinsed frequently on the lowest setting with a water pick and a dab of all natural, alcohol free mouthwash - it made everything feel less gross and cleans out the secretions.... it dependeds on what is setting off the nausea.

However I also know someone who was sick from beginning to end! He said he lost 50 lbs, and spent all his time throwing up - he's great today!! It all ends!! if you find the ensure helps and does stay down, the try buying some protein powder, and adding say. 1/4 of a scoop per bottle of ensure. Would add one scoop to one ensure a day - and found it really helped with healing. One scoop affects the thickness though - so breaking it down might make it easier for him. Good luck!, sorry he's feeling so crappy! Take care!
