At a little over 12lbs, I found I needed to reduce my dosage from 5 to 3 capsules a day. Also, if you are sensitive to caffeine or metabolize it slowly, avoid taking this too late in the morning as it may disrupt your sleep. Taking 5 capsules first thing in the morning definitely kept my focus high but I also had trouble staying asleep at night. Three capsules worked better for me including taking a two day break after 5 days on.

Amazing product

So far it has been nice. I do get some sense of increased mental tenacity, like I can slow my thoughts or speed up my processing.

Great
