A bottle of cold cherry coke, a big packet of salted tortilla crisps, and a bottle each of pulmo bailly cough mixture (codeine based) and J.Collis Browne's mixture (basically a weak solution of morphine, 20mg per bottle, but its OTC. Used for treating coughs and stomach upsets, but also convenient to neck a few bottles before I go off hiking, both for relaxation, and for my knee pain.
