OE? I assume we're still talking about reduce based on the rest of the post...
I would not think this should make you tired, and if anything, the reduction of cortisol should somewhat invigorate you (not acutely per se but with continued use)
There should only be any issue if there were extreme drops in cortisol or extremely prolonged use. For just about any normal use, no issues
I think you have an old thread to reference too
