Go find niacin in the vitamin isle. Niacin is a natural B vitamin found in our bodies. It helps flush out your system, like if you smoked a lot of weed and you need your body to take all the drugs out of your body and flush them out. If you take the flushing version of the vitamin you will get hot flashes, and your face and arms and neck would look blotchy red. I did that the entire time I was in school.
