"If you have to take a stimulant and you get anxiety, this is the medication to take. It is very smooth and doesn't cause anxiety. There isn't a high and low and you don't really feel this wear off (no ups and downs) the way that Adderall and other medicines cause a low in the evening. This is not any more addicting than any other drug so don't believe that. People that require these types of medication typically don't get addicted to them.  People and doctors tend to give medications that can help people."
