I bought these for my wife who currently smokes about 10 cigarettes a day plus she also uses an electronic cigarette. She reports that the lozenges do take away the craving but have a most unpleasant taste and cause a burning sensation in the mouth. She is, however, persisting with them (mainly for my benefit) and alternating between taking a lozenge and smoking a cigarette. Surely the company that manufactures these, could make them more palatable. For those who don't know, each lozenge has to be sucked, it cannot be swallowed.
