Yes. The stimulants used have a side effect of basically being turbocharged coffee.... That's the best way I can describe it.

I've been in prescription ADHD meds for more than a year and after forcing myself out of bed long enough to shove my medication down my face hole, within an hour, of that, it becomes impossible for me to get to sleep for at least 10-12 hours, even if I'm fully acclimatized to my dose.

Once when I neglected to take meds for over a month straight (pretty significant depression after a job loss, I'm ok now), the first time I started back on my medication, I was wired for at least 20 hours after taking my normal dose. Messed up my sleep pretty badly, but I got back on the horse right after and things calmed down a lot.

Since getting onto this prescription, I haven't had any issues staying awake, and usually as the meds wind down (wear off) near the end of the day, I can get to sleep at a reasonable time.

It's a stimulant, so that's not really surprising.

Been on Ritalin for a decade. Helps a lot. Used to be WAY disorganized.
