The thing that I find interesting about soda is that people mention the calories...or the sugar...or any number of things...but you rarely hear concerns regarding the aspartame (which has been linked to migraine headaches, seizures, fainting spells, dizziness, numbness, nausea, muscle spasms, weight gain, depression, irritability, insomnia, hearing loss and tinnitus (ringing), breathing difficulty, blurred speech, memory loss, rashes, fatigue, tachycardia, visual disturbances, heart palpitations, anxiety attacks, loss of taste, and joint pain).
I used to drink at least a liter of Diet Dr. Pepper every day...it was my "treat"...then I lost consciousness (twice) and was forced to look at what might have caused it. I don't know if the soda was the cause, but as soon as I read about the potential side effects from too much aspartame it just wasn't worth it.
