I have noticed this with my husband. He hasn't been treated with
Celexa or
Concerta though. He has generalized anxiety disorder and ADHD. They've tried to treat his anxiety with everything from
Xanax to
Paxil. He is also a prescription drug addict. This is where his over-focused ADD shows. He will have a bad day and will "need" extra meds and he won't shut up until he gets them. Also, he can stub his toe and complain about it for hours! Little things that any other person would dwell on for about 30 seconds and move on. Like you said, it almost presents as OCD at times. Not sure if it's related to the particular meds you're on or not, but it's worth talking to your doctor about. Good luck.
