Hear good things about taking niacin supplements most notably that is can lead to better mood. Well, took my first one today and about 30 minutes after, it felt like my head was on fire. More specifically, it felt like I was maced. My face got flushed and as I said, I felt like my head was on fire. I ended up taking some benadryl and after a while I felt better but when I got home, I looked into it and apparently in some people this is normal and it's called the niacin flush. Oy. When I say on fire, I mean on fire. They say it isn't harmful but fooey, it hurt like hell. It does say that it should minimize if I take an asprin 30 minutes prior so I'll try that but has anyone else experienced this?
