For those who are 'supposed' to be taking it, the withdrawal symptoms associated with inadequate dopamine production do not happen. Also, it has the opposite effect (calms rather than stimulates) and those who are calmed by Adderall also tend to be amped-up/stimulated by opiates (so if opiates act like speed for someone then they can likely take Adderall without the negative effects on dopamine production experienced by those who take it as a stimulant).
That was a fascinating write up TV, and spot on. I've got ADHD-PI and have (supposed to have) been taking Ritalin and anti-depressants for several years.
My biggest problem is that I can never remember to take them. They work really well when I do, but normally I take my first dose in the morning, get distracted, and forget to take them for the rest of the day. Often times, I'll forget for days on end or even up to a week.
When I first began I was really consistent, but after 10-11 months when I started forgetting to take them, I never felt any withdrawal symptoms. I should start setting my 'meds' alarm again. I'll probably have forgotten to do so by the end of this post...
I also don't feel any strong 'up' effect with them. My head is really clear and I can focus long enough to tear through a good book. My memory is sharply increased as well and I remember names, dates and figures that I'd normally never recall. Still, if I take two Ritalin and fail to get out of bed, even after they've taken effect, I'll fall right back asleep.
Funny how they seem to effect people so very differently.
