Welcome to OCF, Brandon! Its great to have you here

Congrats on getting your feeding tube removed! That accomplishment shows you must be doing very well with your recovery.
Dry mouth is a problem many of OC patients have after rads. Its sure better than that thick gunky mucous phase! Many OC survivors become life long water bottle carrying club members after rads. This along with everything else can take a long time. A complete recovery can take a full 2 years. Most patients will notice continual slight improvements in their sense of taste and dry mouth up until about 2 years post rads. Being you are young, it will hopefully be an easier road than for someone older.
Best wishes!
