Why not chew some nicotine gum? People cite things like blood pressure and cardiovascular effects, but seems like caffeine has these same issues and they might just be general stimulant related effects. Have you ever considered if you have add/adhd? You might benefit from adderall as well or some other stimulant. These also have extended release formulations.

I wish coca leaves were available stateside. Not sure the growing requirements, but it seems like they have a lot of similar neuro benefits without much of the harm from the narcotic derivative.

That is just caffeine.
