As I posted my previous comment, Mrs. AZLiberty invited me to a late breakfast of a homemade gluten-free waffle (the Mrs. is celiac) with fried eggs and fresh serrano chiles from the garden. When I started eating I noticed that my swallowing sensation had changed. I usually eat without a beverage so as to allow my digestive juices and enzymes to have maximum effect, but this time swallowing seemed slightly restricted, so that I had to take smaller bites. Then my vision changed, with half of the pixels being replaced by glowing gold dots.
I was giving a running commentary to Mrs. AZL, who started to get worried. She dragged out the blood pressure meter, which recorded my BP as 78/53, with a pulse rate of 62. I generally have a low pulse rate, so that didn't seem out of the ordinary. But my BP has recently been 120 over something, so the BP measurement was definitely surprising.
After a few minutes the swallowing and visual sensations returned to normal. Now that an hour has elapsed, my blood pressure is up to 98/60, and I'm feeling almost normal again.
I definitely wouldn't do this before driving or operating heavy machinery.
Now mine didn’t do that! I took app. 166mg of Niacin, not 500. I know virtually nothing about this but if it effected you that way you might want to back it down and work your way up slowly. That is even recommended by doctors when prescribed Niacin for the first time. I think your body has to adjust. That’s why I divided my 500mg capsule into three parts. I probably should have divided it into four parts. I’m glad your experience worked out OK though.
The flow chart recommends starting with 300 mg niacin and 20 mg melatonin -- and also to take the melatonin 30 minutes before the niacin. Also, "Best with food", which seems to conflict with Dr. Kats's advice to take it with water only.
Next time I'll stick with 500 mg niacin, but jack up the melatonin to 20 mg. Has anyone had experience with taking additional melatonin in case you have breakthrough flush?
