Niaspan ER and cool water

500 mg - started last week. Woke up twice this week with face and neck feeling like the day after a bad sunburn. No itching. Rest of body fine. No rapid pulse. Only the sunburn effect. Lasted about 1/2 hour. Somewhat uncomfortable, but tolerable. Some cool water splashed on face and neck helped.

I,too, am having hot flashes. I take 1000mg in the morning and 1000 right before bed. At night, I don't wake up to feel any effects, but during the day I start having these hot flashes. I can feel it coming on because my ears start to tingle, then feel warm; and it just moves right over my face. I feel like I have a bad sunburn. My eyes start to be shrunk in and my skin on my face begins to droop. I think these are hot flashes. They only last about 5 minutes, but when it's happening at work, it's embarrassing. Haven't talked to the doctor yet, but will bring it up at next appt. Is what I'm going through serious? I hope not.
