I took 200mg of niacin last night about 10 hrs after eating anything, got the flush decently hard, orgasmed 1hr and about 20min after taking the pills. I then went to bed and had an additional 2 "O"s during the night. The next day I woke up early, put on my chastity device (makes me feel like a freak, but it works), had fenugreek + garlic in the morning then fenugreek + green tea around noon. I was then able to get about 30 min of hard exercise (jogging, sprinting, martial arts) and about 3 hrs of light walking outside in my back yard.
