As killer stated you need to test yourself. Your on the right track with the cardio, but you dont need to overdo it on the water. Just keep yourself hydrated while you sweat and workout. Ditch the niacin its a myth and will only cause you discomfort. Vineger wont help you either it will only make you sick. Pick up some metamucil it will help you to void some thc metabolites through your colon. Have you thought about substituting with Quck Fix? I would look into it, you may not be clean in 2 weeks.
