Don't eat or drink anything in the faery realm

One of the biggest rules when visiting with the faery is to never eat or drink anything while you're there. I don't know how it works but supposedly if you eat anything in faery you'll become trapped there. Unfortunately none of the food is actually real so you can starve to death eating tons of stuff. So you wont live long if you do eat the food there. The faeries will throw all kinds of food in front of you over and over until you finally succumb or leave. My suggestion would be to leave.
