- Drink plenty of fluids (a minimum of eight glasses per day is recommended).

- Be sure to include periods of rest between energy-draining activities.
- Mouth care is very important.

This should be done at least after each meal and at bedtime.
- If you have mouth sores, avoid mouthwash that has alcohol. Also avoid alcohol and smoking because they can bother your mouth and throat.
- If you throw up or have loose bowel movements, you should drink more fluids so that you do not become dehydrated (lack of water in the body from losing too much fluid).
- If you have diarrhea, eat low-fiber foods that are high in protein and calories and avoid foods that can irritate your digestive tracts or lead to cramping.
- Ask your nurse or doctor about medicine that can lessen or stop your diarrhea.

- Keeping your pain under control is important to your well-being. Please tell your doctor or nurse if you are experiencing pain.
