Ok My daughter is ADHD, on meds and still has more personality than should be allowed for a 4ft tall 3rd grader, she's always been this way. The right dosage of medication is not going to change her personality just give her the ability to control herself and focus.
I have tried caffeine but coffee doesn't even have enough caffeine in it to effect my daughter so we had to go back to med. We also tried an increase in B vitamin supplements , omega -3s , no sugar, no dyes , etc. None of these had a noticeable effect.
we were on Vyvance and did VERY well on it but just moved to concerta ( I think that's the spelling) because the Vyvance gave her the very uncommon side effect of drastic appetite change.
For the kids that caffeine does work for it does not work as well as medication, does not last as long, and caffeine is an appetite suppressant , that's why its used in diet pills.
Side effects of caffeine can include withdrawal symptoms like headaches .
caffeine is addictive.
in response to " there's plenty of information on the internet" There's also plenty of misinformation on the internet.
