I treated with this protocol five times now, every one was successful with effects lasting up to a year. A similar protocol treats dry eyes and dry mouth. Amazingly, the protocol only calls for two back-to-back treatments. Sometimes I did three. Here's testimonial from one of the patients:
 
"I received a three session protocol from Lok Kwan Cheng to restore my sense of taste which was much impaired for many years. Long a 'happy' eater, I was missing the tastes I'd grown up with. The acupuncture worked for me, and mealtime is once again 'happy'." - Jim Hanzel
