An anemia (noun) is a medication designed to counter weariness. However, to qualify as an anemia it must be neither swallowed, given intravenously nor administered as a patch. Instead, it is a liquid that is injected forcefully up the patient’s butt.
Because of the discomfort and indignity of anemias, one should first try drinking coffee or other caffeine-based drinks as a possible remedy. If that doesn’t work, ask your doctor if you are a candidate for an oral or patch-based medication. Even an intravenous cure might be preferable.
If all else fails an anemia may be necessary. Or you could just live with your exhaustion. It’s up to you.
