how did he know your infection is already for 5 yrs? what if your infection is caused by Grapefruit-Seed-Extract burning your nose?
i've seen some people here make thread they're "cured" only to come back again later.
i'm also considering that Grapefruit-Seed-Extract just not yet totally convinced how it is related to BO. i can understand bad breath but BO doesnt make sense. anyway, i'll wait later i'm sure if it works others will start posting.
