Even the most reportedly benign malaria drugs may have unexpected side effects. Remember this while you are taking them. The entire universe will suddenly get spectacularly more irritating, but keep in mind that it’s your perception of it, not the universe itself, that has changed. Except for the parts of the universe that consist of your companions who are also on malaria meds, because they are experiencing the same thing. Pissing matches and some shouting may occur. Don’t take it personally. Remember that it’s the drugs talking. Remind one another of this periodically.
Quarantining yourself when you are feeling particularly aggressive is a good option and will be appreciated by the group as well. Again, don’t take it personally. You may have non-scary but very vivid, exceptionally detail-oriented dreams. Try bonding with your companions over them instead of snarling at each other over literally the most irrelevant things imaginable. It’s better for morale.
Thank your lucky stars that tomorrow is everyone’s last dose of Malarone, and you’ll be back to your regularly scheduled programming shortly.
