A heavy caffeine user, I also have occasional seasonal allergies (a week per quarter?) and rather than take simple Loratadine, I always prefer the versions that include Pseudoephedrine. It noticeably gives me a bit of extra pep to push on through the sniffles. I'm honest with myself that caffeine is a drug, and that my occasional consumption of Psuedoephedrine is a step away from being low-grade meth user. So would I use something with cognitive benefits at concentrations (or consumption rates) that exhibit no harmful effects? I already do.
