About 20 minutes after donating blood during a blood drive at the public library, you find yourself lying on the floor in recovery position realizing that the water, coconut oil and nuts picked out of the only non-carbage snack provided were insufficient to compensate for a liter of lost blood. When the shakes, sweating and nausea subside enough to do so, you mix up a concoction of bone broth, sea salt and exogenous ketones, which you carry with you in your bag for 'emergencies.' Despite a couple of additional episodes of decompensation, you manage to drink, and eventually keep down, enough of the magical potion to be upright. You do all this in a glass-enclosed study room at the local library, visible to all, but drawing no attention to yourself. Nobody notices a thing .
(PS You know you're a health care provider when you deliberately avoid seeking help because you don't want people messing with you .)
(PPS Note to self: when donating blood while fasting intermittently, consider eating a meal BEFORE the blood is taken .)
