Yeah, same, perhaps more of a 'calm me down' than 'sleepy' reaction in my case, but usually it just reveals that once calm I could/should in fact sleep some more.
Coffee after I take my concerta makes me feel sleepy almost immediately. But I still enjoy the taste so I'll still drink it. (I have yet to find a decaf coffee that tastes the same as caf, it's weird.)
Yeah, same. And I don't even have a preferred taste - I almost always buy different coffee and alternate randomly between preparation methods (or even just the grind with the same method and same grains).
I guess I just like the process itself, not as a ritual or habit, but a simple and totally different task to what I'm doing at the time.
