I normally sneeze three times in a row, one or two times a day - if it happens more than two times, I know something is wrong. I purchased the Zinc lozenges because winter is coming and I have heard that zinc is effective in stopping it if it'scaught early, and because I've been satisfied with other Advanced Bionutritionals's products. I didn't need them for several weeks, then I started to sneeze a lot, seven and eight times a day. On the evening of the second day, I took one of the lozenges before going to bed. It cleared up immediately and I didn't sneeze again for a week after that. You have my highest recommendation.
