My husband had radical cystectomy 3 1/2 months ago. Due to cycles of diarrhea and constipation, his doctor prescribed Linzess ( 1 or 2 a day, 30 minutes before eating) He now has sores on his lip, and a great deal of mucus in his mouth, with difficulty tasting anything. He is able to swallow liquids and is well hydrated, but very lethargic and depressed.
