Review: I bought these for my mom who has had sleeping problems for a while. She said that these pills makes her feel well-rested. Often, she wakes up feeling like she has slept longer than she actually did. It is a good product!
Review: L-Serine does work at 4/night. The only reason for the 4's are due to ... it does take a couple of weeks to feel a difference; they do make you want to use the bathroom quite a bit until your body gets used to them; and they are on the expensive side due to needing to use them continuously. When using, they make you feel if you are picking up information in a file cabinet you haven't used in a very long time. It gives you a the benefit of remember things that you forgot you had remembered.... it helps with focus to finish tasks that you could not complete before; you feel years younger in the brain instead of feeling 'aged'. I did take it right before going to bed but stopped taking that close because it gave too much energy and could not sleep; but when I took from 2-3 hours before bed, I started to get somewhat sleepy, but not enough to stop doing what I needed to do. By the time I went to bed I was very sleepy and was ready for the Z's and could sleep a good 5-6 hours before a bathroom break. This is good when you could only sleep 2 hours before there was a disruption in your sleep. Love L-Serine and I know over time it will get better and will get more hours of sleep as it covers all of my serine needs.
