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.
"There is a Catskill eagle in some souls that can alike dive down into the blackest gorges, and soar out of them again and become invisible in the sunny spaces... even in his lowest swoop the mountain eagle is still higher than other birds upon the plain, even though they soar." -- from Moby-Dick
