ADHD
"My 20 y.o daughter was diagnosed with ADHD last year and has been on methylphenidate since January 2014.  The dosages have varied and she is able to take them as needed.  Her concentration and grades have improved tremendously.  The first side effects were loss of appetite and headaches.  The headaches went away after a couple of weeks and her appetite has returned somewhat.  However, over the past 5 months she has developed palpitations.  Her cardiologist, her psych Doc and primary care Doc are all monitoring this. I&#039;m not sure where this will end up."
