St. John's Wort is great. Buy the standardized 0.3% hypericin 300 mg capsules. I take it at night since it makes me drowsy. Start with one capsule at night then perhaps take two a night if you feel you need it. It takes some people a week or two before they feel its effect. Don't take St. John's Wort if you are taking a prescription antidepressant. Consult your physician before taking St. John's Wort if you are taking other prescription drugs. The main side effect of St. John's Wort is sensitivity to sunlight. It will make you sunburn easier, and make your eyes more sensitive to irritation from sunlight. Wearing sunglasses in the bright sun is recommended.
