Tom thanks for your reply. My husband goes through the vomiting sessions when he has his chemo treatments. It is very painful for him. I currently give him between 64 oz and 70 oz of water daily and I give him 2 tsp. Guaifenesin via his tube every four hours. He also gargles with the Guainfenesin. Did you use anything else to ease the secretions? My husband would be better able to handle the chemo side effects if he did not have to deal with the secretions. The oncologist is planning on two more chemo treatments and then after several weeks a PET scan. Any and all advice on what we can do to alleviate radiation recall side effects would be greatly appreciated. Eileen
