Refined sugars and caffeine really fks me up. I tested this hypothesis yesterday. I had a Snickers bar, and a can of sweet lemon soda, followed by a bottle of lemon ice tea an hour later. None of these beverages were of the “sugar free” variety. My speech suffered for hours afterwards. There’s definitely a correlation between dopamine surges and my fluency. On days where I only drink decaffeinated coffee, water and herbal teas, my speech is actually pretty good. 👍🏼
