Good Morning! I have been getting chemo, immunotherapy and Keytruda. Had 8 treatments so far every 21 days. I did skip one full treatment was tired of being sick 8- 10 days and try to recover next 10. Only food I ate was when I took my pills like crackers. Wait 5 minutes and if they stayed down than would take pills. Just got very weak. Go back for next cocktail on the 14th. Next scan on November 4th to see if tumor stayed the same or growing. I have same cancer your dad does but was told by 4 different cancer Drs it is not curable but treatable to keep me comfortable.
