Niacin (sublingual)

[Onemorestep]

Every time I take this sublingual niacin it causes pain for a few days afterwords. Anyone think of why? It's irritating because it's great for my emotional state but I've tried enough times that it's confirmed. I believe it does interact with the immune system. Any suggestions would be great!
