I got a bottle of liquid LDN. It says to store at room temp. but I remember some people saying to store it in the fridge? For those who take this, how do you store yours, and do you find the LDN stays good in the fridge for a long period? I remember someone saying it could be good even for a year? Do you drink the liquid LDN straight (after measuing obviously) or mix with water, etc? Thank you!
