I took the product first thing in the morning before breakfast, as suggested, and had zero issues with nausea or other issues. I noticed a better ability to focus and stay focused whatever task or project was at hand.

Definitely removed the irritability part.

For Week 1: I have experienced a slight increase in focus and cognition which is great, for the first week i have started with just 4 capsules per day and 2 days off on Saturday and Sunday, i do notice a decrease in productivity when i am not taking the product so hopefully once the 4 weeks is complete i am able to retain some of the benefits permanently. For Week 2: I have began experiencing significant mood elevation as well as superb task based focus, my memory is out of this world. I work s a software developer and this product Is really helping me push through projects with near perfect recall on bugs that need to be fixed and features / functions that are required to be implemented. Previously I would have to go on a search engine to look up features that need to be included in the code base but now I can just recall what needs to be added. This product is a game changer.
