I added niacin to my daily supplement list today. My goal is geared towards improving my cholesterol, lowering my BP, and possibly improving my skin. The 250mg initial does gave my my first flush ever. I didn't turn red, but I felt a pretty good buzz there for about 30 minutes. My head and scalp in particular had a nice warm glow. To be honest, it was not a bad experience. It was weird, but almost pleasant.

For cholesterol, higher doses are the norm. I may try to work up to 1g per day should I not have any significant issues with niacin. If I do, I'll follow Rob's lead and dial it back to a level that works. So far so good.
