I'm not sure when you say stopped up whether you mean the Big C type or the Peg is malfunctioning?

I didn't have a Peg and because of that I didn't drink enough calories or water in the latter days of my Tx and I became dehydrated and with taking various pain meds all that lead to the Big C. So the Big C can cause nausea; the pain meds can cause nausea; the radiation can cause nausea and my chemo causes nausea all of which doomed me to severe nausea which like a snow ball rolling down a hill made me get less calories and less water which continued my dehydration which lead to ..... you get the picture. Things that helped me were getting some IV fluids, Carnation Instant Breakfast VHC, the end of my radiation and chemo and stopping all my pain meds.
