Hi guest,   I had chemo in 2003, I was still able to sing in singarounds , it didnt affect me at all, Although I can assure you chemo certainly has different effects on different people. My friend and I went through chemo together and she was ill after every session where as I was lucky enough not even to be sick once, although I did sleep well on the same night as treatment. Other than that I had a normal social life. Hope you have the same results as I did. Good luck with ya treatment for a speedy recovery.... I will think positive thoughts for you.....Suzi
