I take no regular medication, but in this last year I have begun furtively taking pseudoephedrine hydrochloride, 30 mg per tablet, plus ibuprofen 200 mg per tablet, two tablets with breakfast, nearly every day. Within an hour my head is clear, I am calm, able to focus on my work or tai chi practice and feel benevolent toward the world. This continues for about five hours. No urinary problems, no hallucinations that I know of, just calm well-being. Doesn't seem right, somehow, but it's hard to give up simply on principle.
