I am not advocating giving up meds without discussing this with your doctors but I was one that couldn't shake my constant nausea until I finally stopped taking all my meds. My docs were skeptical that my meds were my problem but it did stop my nausea and allowed me to keep food and water down and it made a big difference. Note that I did not have a Peg to fall back on so I had to swallow all my food and water.

I'm also not a pill expert but the list of meds your husband is taking seems excessive; perhaps overlapping or perhaps the wrong combination but that's just my uneducated opinion. Has he been seen by a Pain Management Team?
