I've used them but honestly, they aren't really worth the money. They work just as well as any other type of hard candy or suckers. Some of the flavors are awesome, like the lemon but some of them, like lavender, are just gross. Haha. For me, the morning sickness is triggered by being hungry or having a dry mouth. So, I find that if I eat snacks often(even if I have to force myself) or suck on hard candy, it really helps with the nausea a lot! I've tried green apple BNatal lozenges too and those are just gross and make me even more sick!
