I've been reading up on niacin lately and I've heard of it helping with schizophrenia and depression, maybe it would help with anxiety?

I'm not depressed, but I have noticed my mood is a bit elevated since I started taking it.

I suggest if you do want to try it, read up on taking niacin. It can cause a flush which is very uncomfortable and if you don't know it is coming, it is scary.

It's possible to completely go off diet soda. I haven't had one in almost two years. It was hard - I went cold turkey for two weeks as a test of willpower - and when I tried to have one later it tasted like chemical soup! I do drink some caffeine now, just not with artificial sweeteners.
