I've been on Memantine at 10mg/day for over a month now. I can focus better, it's easier to motivate myself to get things done, and I'm procrastinating much less than I used to. I've been much more productive at my job and around the house. Best of all, I've had absolutely no side effects other than a bit of dissociation and brain fog for the first week after increasing my dosage to 10mg (and even that could probably have been avoided if I had titrated more slowly.) https://www.reddit.com/r/Nootropics/comments/47e6p7/memantine_is_the_best_treatment_i_have_ever_tried/
