The mouth lozenges for dry mouth were excellent at first, but I have dry mouth all day, and they started upsetting my stomach. I guess I was taking too many. Since I switched to the spry, I don't have a problem. I keep the a small bottle of the spray in my pocketbook, because I need it sporadically. It is probably different with each individual.

Clean ingredients, actually sour

Flavor Name: Tangerine, Watermelon, Blue Raspberry

Absolutely wonderful! Actually sour and love the ingredients most of all. I can love sour drops again like when I was a kid without the terrible “everything unnecessary added” I bring these on flight trips and when I crave something sweet.

Perfect, if a lil pricey.

Flavor Name: Tangerine, Watermelon, Blue Raspberry

For starters, more intense than sour warheads, with better core candy flavor, by a lot. yea, a little pricey for the quantity, but if you want a sour punch in the mouth, with that "hurts your jaw, but in that oh so good way", tingle your brain -kind of sour. you won't regret these. I bought more flavors already. I never leave reviews, I hope this helps your decision making. Oh, and my mouth hates me right now, 'cause to many, are gonna hurt ya! WORTH IT.

Very good!

Flavor Name: Tangerine, Watermelon, Blue Raspberry

Very good sour hard candy. I was instructed to use sour candy by my doctor for clogged saliva glands. Very hard to find this type of candy in the stores. A little expensive and some of the candies are not consistent in size, but acceptable. Recommend
