This is how I'd put it. I've been diagnosed with adult ADHD and take a moderate to low dose of Adderall under the direction of my doctor. I can easily forgo taking it for weeks, and do so. These "vacations" without it were advised by my doctor to prevent tolerance buildup, and I suspect to diminish the potential for addiction. My dosage has remained constant and I don't feel a "need" for it, so I guess they work. For many of those with ADHD the drug makes a world of difference, and pushes focus and tendency to move around into the "normal" range. For certain activities the (benefits - costs) equation works out, while for others it does not (which is to say certain activities don't appreciably benefit from the quiet mind--the costs are long term and are more difficult to discern). It's about planning to take it for days where it does help, and being mindful of the health ramifications (staying hydrated, eating normal and healthy meals, monitoring cardiac health with support from a doctor, continuing to consult the doctor, etc.).

My biggest fear beyond addiction is that it will be detrimental to my memory and learning in the long term. It's difficult to know if that is true.

The author clearly abused it. Taking it "to socialize" seems weird to me. I suspect the author did not need it in the first place, and was already in the "normal" range. My mentally disorganized self is much more outgoing that the focused version of me. If it is impacting sleep, the dosage is probably too high or too extended (though many MDs prescribe the XR version since ostensibly it has less potential for abuse).

Some of the alternative pharmaceuticals may work about as well, but Adderall has been around for so long that its risks are fairly well understood--though less so with long term use.

Vyvanse is a means to extract more money from patients via patent protection. It's essentially dexedrine with a lysine attached (new side group=new patent). The lysine gets cleaved in vivo, and it becomes dextroamphetamine. Adderall is a mixture of dextro- and levo- handed salts, so it's a bit more nuanced.

Taking it without doctor supervision is a major risk, and taking more than is prescribed or mixing it with other drugs as the author did compounds the risk. The potential for abuse is real.
