Been dosing it at 1 cap 3 times a day for a little over 2 weeks. I have noticed that my thinking is clearer and less cluttered. My time solving Sudoku puzzles has gone down quite a bit. Can do the expert level in about 10 minutes compared to 15-20 before. I have also noticed that my memory has improved. I can still remember measurements from last week for 4 pieces of plywood that I cut. The down side of this is that my sleep hasn't been as good. Just seems like my mind won't shut off too well when it's time to go to sleep. I still get to sleep and wake up not feeling too groggy but it just seems like I'm not getting to my R.E.M. sleep. Maybe I will try not taking my last dose at supper time and see if that helps. Overall though, I'm am liking the effects so far.
