Like Blair, I ended up using Prilosec as well. Not for constipation but for acidic grossness deep in my stomach. My oncologist thought it was responsible for much of my nausea. So about 1/2 way through 8 treatments I started that as well and I felt so much better which in turn helped my eating and drinking. So I guess it was all related after all for me. The prilosec is pricey but SO worth it!
