Amino acids are also great. Agmatine (1g 2x a day) for PTSD/depression, it stops the negative emotions. ALCAR (750-1g) for morning energy/motivation/fat burning, lasts about 8 hours for me, gets through the work day better than coffee. DLPA (1g) for mood (see "Mood Cure" book), I take this in the late afternoon after the ALCAR is wearing off, some take it twice a day though, amazing for mood and making all 5 senses feel better in general, then NAC (1g for OCD/irritability/addiction impulses, or 600mg for allergies/cold/flu). Glycine (3g before bed) for deep REM sleep.
