This is a round white pill with a single line through the middle of one side. No other markings. The pill is small but seems a little thicker than aspirin style pill. I have been informed that it may be Niacin or perhaps some sort of caffeine pill that may be sold over the counter at a convenience store. Thanks for your help

There's no way to say, the description is too vague.
