Nausea revisited

I just finished 25 rad treatments last week.  I've been having difficulty with nausea and loss of appetite, and GI symptoms worsening over about the last week or two of treatment, particularly bad now.  Also the fatigue is really setting in only now.  My skin held up relatively well, mostly like intense tanning and some sunburn, but no blisters.  I became concerned about the nausea so I looked it up on this site.  There is a brief but "definitive" article regarding the issue and attributing this experience to confusion with rad vs chemo SE.  I did chemo relatively well and had them take be off all the ancillary meds I possibly could, I had more trouble with them, than the chemo.  I'm a very sturdy person, and don't tend to overvalue every little ache, pain, and the rest of these things  So I wanted to open a forum to revisit the nausea issue.  It's not that I want it treated particularly, I think it will pass.  I just want to get feedback on other's experience.

Thanks for your help.
