Hi Smitty,
1) Hydrate, hydrate, hydrate - 2-3 liters per day
2) Let your doctors and nurses know what is really going on with you on how you are feeling physically and emotionally - do not be hesitant to take medication for anxiety, ativan is good for that
3) Get the good anti-nausea drugs and be proactive in using them - zofran worked well for my husband with compazine suppositories for break through
4) Pain medications are critical - my husband hated the short term meds because they made him loopey but found that the long acting duragesic patch did not have those side effects and controlled his pain well
5) baking soda and salt swish to rinse your mouth, magic mouthwash or lidocaine solution or gel for mouth sores
Don't forget to keep up the daily flouride and mouth care, and try to stay positive. Remember that we all have bad days and if that happens sleep it off and try again tomorrow.
Best wishes to you - Jack finished his radiation 4 weeks ago and had his last cisplatin chemo today.
