My general practitioner that I see told me to put dark chocolate powder in my coffee and take a balance of Omega 3,6and 9 fatty acid oils. I notice when I run out of the Omegas’ and if you can’t tolerate caffeine then don’t drink the dark chocolate. I also take a lot of vitamins and minerals especially “B” 3 Niacin in the form of “nicotinic acid” , the kind of B that causes the flush but the flush doesn’t last long and was recommended by the late doctor Abram Hoffer who did studies on using vitamins as adjuncts to our SZ medications from the late 50’s. That form of the B vitamins is known to reduce bad cholesterol as well as clean other toxins form the blood.
I was on an antidepressant (cipralex) for several years, just got off 1 month ago completely. It did not take away my anxiety, though it did make me more energetic and gave a noticeable mood boost. if your anxiety is strong (OCD, PTSD), I doubt an antidepressant would completely solve it.
