niacin flush and alcohol

just a few questions about the niacin flush. i was reading this

http://www.healingnaturallybybee.com/articles/niacin.php


and she says that the timed released forms of niacin are more toxic than regular niacin.

i always have very pronounced flushes when i take niacin.

also i get the same flush when i drink even small quantities of alcohol. but i seem to feel a bit calmer when the flush is over so maybe it actually is working. could it be that alcohol is somehow good too since i also get calmer from the alcohol flush?

does anyone know the relationship between alcohol and niacin?

if niacin is causing the body to detox then is it good to so a sauna while you are doing the flush?
