The chemo hit me 2 days after the 1st tx, but only lasted about a day and 1/2. Radiation didn't really hit until the end of week 2 when I found that everything tasted like week old garbage and I was having a hard time swallowing. Seems that your Dad's nausea is probably like what hit me and hopefully has gone away by now and the rad. effcts will hold off for a while. Good luck.
