The constant dryness in my mouth and tingling and burning sensation which is worse on my lips is horrendous. It is making me feel like I do not want to live.This is the most annoying condition I have had to do with PBC, although the itching in my head has now stopped. The doctor has put me on a low dosage of anti-depressants to try and calm the nerve endings down, but I am at the end of my tether. It has made me feel like ending it all as I cannot carry on like this. Has anyone else had this and what have you taken? Or would there be any foods that you would recommend to avoid. I am aware now that I need to eat various foods, but would like to know what's best.
