smoke gets in your eyes!

I just took my daily supplements (too many to list here) but the two last were B complex (hate the taste and smell) and Selenium, with not a whole lot of liquid--the dregs of my tea. A minute later smoke came out of my mouth! Am I hallucinating? If I am hallucinating, please don't tell. Or perhaps I'm overdosing on supplements? Do tell on this one. Thanks.
