I have ADHD and contrary to everyone's reports, coffee and similar drinks made me sleepy. I don't drink them for this reason. Now I've read a lot of times that people with ADHD tend to experience the above mentioned effects and I wanted to know how many there are of us. I tried to come up with answers that (almost) anyone can identify with, to gain an insight on the different directions it might go. It's just for me, not any research paper. Beware of the Captcha though. Thanks in advance!Your vote: Coffee and other similar drinks tend to increase my heart rate but makes me sleepy.
