Is xanax an benzo

No. It is the opposite of a stimulant. It is considered a minor tranquilizer or sedative. (that being said, some people do report increased activity after taking medications that, in most people, cause sedation. Another notable example is Lortab/Vicodin or any form of hydrocodone. Many people find it to increase energy and give them "drive" to complete tasks even though the drug is generally sedating.)
