Daughter used to wake up and the nose would go. Sneezing and all things allergy. Halg a box of tissues later the anti-histamine might start to work. Two days of this and she's normal again. They said it was not going to be stocked anymore but I found it on iHerb thank goodness. Ordered it on Thursday and it came the next week. She had just started a bit of a sniffle and straight away it stopped when she started to take it again. Telling everyone to try it! And to get it from iHerb. Thank you .
