Thanks Penny. Your post was helpful. She had me fill out an ADHD questionaire and prescribed Adderal XR 10 mg. In trying to research this med there are sites saying that people develop tolerance to it, then have to get higher and higher dosage … that dopamin receptors “down regulate” in response to the med… making one more deficient in the end (worse off than if they had never started it). One site I read said not to take it more than once a week for this reason ! Is this true that everyone develops tolerance? It seems to me that if this was the norm that no one would have had success taking Adderall XR long term (at same dose) … and there are people that do take it that way ?
