Here is an update from when I recently wrote in about my experience of being "overly-energetic" after taking ACV. Upon further reading, I know now that ACV is a natural stimulant and the website for a popular brand of raw, organic, unrefined ACV 'with The Mother' actually recommends taking 1-2 teaspoons 3x/day, diluted with water (honey optional). OK, so now I understand why I've been bouncing off the walls the last week, feeling like I just downed coffee (very racing, manic feeling). Here's my new plan: 1 TEASPOON ACV with 7 oz. water and 1/4 tsp baking soda. I may take less or none with dinner because I'm not sleeping well. My husband is also sensitive to caffeine and he has had a similar experience to mine. I still love my ACV & what it's doing for my health - goodbye brain fog, depression, acid reflux & hopefully back pain!! Don't give up, folks, & God bless!
