This is sooo good! I just made it up one day... and it's so easy and so refreshing.
Grab a lemon. Slice it in half. Use one half and squeeze all the juice into a glass. Take the other half and slice into 3-4 slices. Squirt one long dollop of honey in the glass. Drop in lemon slices and a few ice cubes. Fill the rest of the glass with water. Stir vigorously. Add more honey as desired.
