Ritalin / Addy causing drowsiness?

[Zobra]

If you are truly ADD then the medication will slow you down and most times make you sleep. I can take 20 mg of Ritalin and fall asleep at the drop of a hat. Stimulants have an opposite effect on someone that has ADD. Most doctors that prescribe it doesn't understand that basic concept.

That's interesting, actually.  Because years ago when I heard about people using Addy and Rita for energy and studying I was like, wait I thought those meds were supposed to calm down the hyper hypos!  That's why they gave them out to "active" kids so readily.  I have no idea how that works, but relating to my experience it seems to make a little more sense.  

I'd also read of some people being sleepy on it but they just weren't taking the right amount.  I took a double dose (still low) yesterday and for once it didn't send me right to bed so maybe that's the ticket.  Still, I hope I can find the right doc around here to help me.  I've never been to a psychiatrist before but perhaps its time.
