Debalou,
Like Meesh stated even baby food burned going down. I am exactly 2 week past radiation and still experiencing soreness and ulcerated mouth sores. Tongue is still slow to respond with taste being limited to salt. Sweets are sometimey and only hints are coming through, not actual taste. Small success with vanilla milkshakes with vanilla instant breakfast in them. Small success with broth and potato soup with broccoli, only about 1/4 cup.
Everything flour-based like bread, crackers, etc. is pasty and abysmal. Gatorade in tiny amounts is alright, any more is uncomfortable. Room temp water is ok, cold stuff is gradual in getting used to it. The milk in the milkshakes is comforting though-doesn't affect my ulcers or hurt my tongue.
About 10 days in, last Saturday, my voice suddenly got stronger and the phlegm subsided-literally overnight. Each day has been a notch better. I hope your situation is the same with each day bringing more and more comfort and strength.
All the best!
