I find whenever I drink coffee that has a bit too much caffeine in it I become rather jittery and full of energy, also my heart speeds up. There isn't anything new and exciting about that. What I do have a question about is that fact that minutes after I drink it and maybe for the next hour or two I find myself thinking better, clearer and faster. This is the same effect I feel when I take adderall to study. Without it my brain feels slow, sluggish and I have a hard time remembering things. To me it almost feels like my heart is pumping faster and pushing more blood to my brain and thus it works in overtime. I would give anything to always feel like this or even 1/2 the level on a daily basis without having to take any sort of medication or stimulation like caffeine. To be honest I don't even know where to start with this. Is this just part of my ADD and there's nothing I can do about it? Or is there another medical condition that could cause this? Pretty much I want to find out if anyone understands what the the hell I'm talking about (lol) and can steer me in any sort of direction. Thanks in advance!
