Sick again. Cancelled PT for the rest of the week. I think I'm reacting badly to something in my diet. My digestive tract isn't functioning right this week. At first I thought it was the Coumadin, but I've been on the drug for seven weeks and not had problems until now. Also, I've been consistently been on the lowest INR levels for the drug. I might need to eliminate dairy and wheat and see if I improve with either gone.
