Ultimately I couldn't use it this way more than a few days a week or I'd get lower back pain. I've also tried steeping ephedra tea but did not notice any effects on concentration.
Later on when I was formally diagnosed and prescribed proper meds I was placed on Adderall first and had similar unwanted side effects after a time. Ultimately, I settled on Dexedrine and no more side effects (other than insomnia if I take it too late) and haven't felt a need to up the dose for years now. It does still have decongestant effects like the other two.
Considering I'm caffeine dependent and can't cycle off daily intake without crippling headaches, where I cycle Dexedrine off on the weekends/holidays without any withdrawal effects, I'd have to agree: So long as it's a therapeutic dose it's on-par or safer than coffee.

Adderall (dl mixture) is just not the same. We know Adderall tends to exacerbate acne and some forms of dermatitis but we don't know how much. We don't know if the pupil effects contribute to driving incidents. We don't know if dry mouth from Adderall is worse for dental health than the dry mouth that some people get after heavy espresso or other stimulating substances, like pseudoephedrine. We don't think the risk of paranoid behavior is high but it is higher than coffee, of course.
And of course some not insignificant portion of the population can tolerate coffee or pseudoephedrine, but we're not too sure about Adderall. Schizophrenic, bipolar, OCD individuals, those with tics, tachycardia, etc, need to tread carefully with stimulants, even maybe sudafed.
