I used to drink Noonbrew for years until they discontinued it. I was devastated and searching for something to replace it when a targeted ad came on my instagram feed. It just may have saved my life because with this I am able to focus on work which is very hard with ADHD. I split up the pack and drink half in the morning then half at lunch which works for me! The focus is amazing and no drop off. Sleep does come better at the end of the day. Overall it is much better tasting and the formulation is worlds above Noonbrew. The customer service is also phenomenal and the founder is super passionate about this company and how the products can improve people’s lives. This is just my honest opinion. Try it! You have nothing to lose! Focus and clarity are yours.
