    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!
