Here's the real list, sorted by how likely you are to meet each one — from the tongue-tingle almost everyone notices, to the nausea you can engineer away with timing, to what genuinely heavy daily use brings, to the medication cautions that matter, to the rare and contested. Each effect is tagged by tier and paired with the practical fix. Not medical advice.
