Engineered staple foods in stock are a blessing with ADHD. Don't even have to think about how much you need if meds took the appetite; they typically come in 500 kcal units.
I'm currently trying to get away from using them for 1 or 2 meals per day, but it's a great fallback option.
Also, how often did I NOT do a nice trip idea because buying, making and packing food seemed overwhelming?
It does feel too good to be true. But I suspect that, while the intended regulation of neurotransmitters in the prefrontal cortex may not diminish too much, other effects of the stims, e. g. on the vegetative system, which cause much of the rush, are just like recreational drugs - they'll fade unless the dosage is increased more and more.
