My mom is 78 yes old and has had fibromyalgia for 15 years. Lately she has fallen twice and is cold all the time and is so weak she can't scoot up into bed. This is a woman who has always been active healthy and lived on a diet of vegetables lean meats and could out do me ,her daughter and I. 30 years younger..after numerous tests and doctor visits I am desparate..I know the Cymbalta is making her act like a zombie. She also takes Evista and a water pill that has hydrochlorathorazide (sp?)..and is allergic to sulfa..she also constantly itches from head to toe....any ideas? The new thing is she's freezing and constantly drinking water
