At about week 5 I went through another round of nausea. I did not have a peg. The only anti nausea med that worked for me during treatment was zofran and it did not help with that last round of nausea. I had to live through that one. I lost a little weight to because I couldn't eat. I'm 11 wks post tx and I am only having slight success with eating. Maybe a baby seving of solid foods a day. My taste is getting better but still no saliva. Good luck with this. I would definitely contact my docs about the stomach symptoms.
