You would need to be careful using it, as it has addictive properties, but if you need a stimulant, you could ask about dextroamphetamine, which is basically Adderall.

I had dextro a few years ago, but only for a little bit. It was good, almost *too* good. Buzz buzz buzz. But I didn't get involved with it because the doc I was seeing at the time switched me to a time-release Adderall, which I didn't like at all, so I gave up on the whole thing.

But might be good for you if you're feeling down down down.

But he grew old, this knight so bold / And upon his heart a shadow / Fell as he found no spot on the ground / That looked like El Dorado.
