I've no first hand experience here, but I can imagine there being tradeoffs. For example, I think creativity is somewhat negatively correlated with memory. Or, I'm often more productive when I'm tired because it's easier to focus. So going into an altered state of consciousness might still be beneficial or preferred even if it has tradeoffs.
