    Both my wife and I are experiencing longer night sleep without feeling drowsy the rest of the day.

    I had been many different medications over the years for anxiety, bipolar & sleep disorders but always continued to have some symptoms with TONS of side effects. 3 yrs ago I tried Doctors Best L-tryptophan and it changed my life! I combine it with St. Johns Wort and get in my Omega 3s and a good multivitimin. The best part is, NO SIDE EFFECTS!!!! Doctors Best has the 'best' products on the market!

    I was a little concerned about ordering my supplements on line but I've very pleased at the value and perfomance I'm receiving. I had decided to try this service with one item and just ordered the rest of my amino acids from iHerb.com!

    I think this does help me to sleep more deeply, with no side effects the next morning!
