Ay yi yiii. Could I talk about Aspartame, Phenylaline, etc? Yes. 20 years ago for a short period of time, I learned the hard way about it. Took a bit to figure out what was causing the massive headaches, mood swings, focus deficits, and every else that goes along with it.
Today it is unprocessed honey, stevia, but before that... just foods that have their natural flavors. They way it should be. No need to pump up the volume.
