Welcome to OCF! Recovery can be a very long road. It will take many weeks before you begin to get back to your old self.

Try using a waterpik on the lowest setting with a mixture of warm water and prescription mouthwash like peridex. Every day at least 4 times per day you should be rinsing your mouth with 16 oz warm water, 2 tsp baking soda and 2 tsp salt. This will help with both the ph balance and healing. I know you said you cant tolerate the salt so cut it back to 1/2 tsp. Push yourself to get some salt into the rinse so it is most beneficial.

Hang in there, it will get easier as time goes on. Until then, read both the posts on the forum and the main OCF pages and learn about your disease and the recovery phase. Your intake is still as important now as it was during treatments. Every single day for at least the next year you should be taking in a minimum of 2500 calories and 48+++ oz water. Those figures are the bare minimum, more is much better. Also drinking lots of water will help your mouth issues. Try to push yourself to take in 64 oz a day.

Good luck and dont be afraid to ask questions, we will help you get back on your feet.
