Hello, niacin is known to cause increase in heart rate, which may occur individually or due to flushing relation, however a night dose causing it after waking is something I would be averse off. Also niacin would have been used to bring your good cholesterol HdL up and if more than 40 you may stop it. If used for ldl I would prefer more safer and effective drug life like statin to be used. So if due to the drug you may stop it for three days and see if you still get it, as stopping for 3 days wouldn't create any problem and you can surely do that. If not occurring daily and some day it might just be due to a a anxious dream..
In most probability because it stops as the day progresses and you start exerting it doesn't point towards the heart.
Lastly I would like you to do a thyroid profile test.
