Very helpful. According to my dowsing I should be on this for 2-3 months. I will review after each bottle. I use 5 drops a few times a day (4-5). I also use the “optimal learning formula” morning & night for memory, focus & better thinking process. So far I am having great results but if I stops for a few days I notice the difference. This too will need a few months to really anchor the right energy. Since ADHD is a brain issue the two formulas work well together. I started a journal to document the results so I can narrow it down to which particular essences are bringing the changes. Thank you for creating Pacific Essences. Thank you for inquiring.
