5HTP, Thyroid: 5-HTP (5 hydroxytryptophan) available at a health food store, is a precursor of serotonin. Take 200 mg at bedtime on an empty stomach. For PMS, try natural progesterone cream, 20-40 mg per day on days 10-24. You may also be hypothyroid, a frequent cause of PMS and depression/anxiety. See Dr. Broda Barnes' book, Hypothyroidism, the Unsuspected Illness.
