If you have a different caregiver on any one of the weeks, the dietitian will train the new caregiver to record food and drinks on these days. The study researcher will collect the food records and give you a fatigue questionnaire on Days 14, 28, and 42. It should take about 30 minutes to complete. If you are not scheduled for a clinic visit on these specified days, the study researcher will meet with you on the first visit following these dates.
