I'm trying Niacin both for getting off of Clonazepam and for anxiety. I need more instructions on how to find my optimal dose. I took my first 100 mg pill after a meal and had significant flushing about an hour later that lasted for 30 min. Dr. Abram Hoffer's optimal dose was 3,000 mg (1000 after each meal) but said everyone is different. How should I go about finding my optimal dosage?
