I take xanax (alprazolam) .25 mg three times a day for panic / anxiety. i am a big guy (250lbs). is that a high / habit forming dosage? what is a high dosage?

With all due respect, your response here is interesting. This patient has not shared how long he's been taking this medicine (which is actually low dose), who prescribed it (possibly a primary care physician?), or whether he's also involved with psychotherapy (CBT is very well researched for anxiety and could help him). At least temporarily, many people with panic need support from such medications while working in therapy for anxiety. The goal is not to be on them forever, and we don't know where he is in his journey. With so little to go on, how can any of us judge something to be "bad medicine"?? While not my preferred choice, Xanax is one that does have to be taken regularly to prevent panic attacks -- otherwise there will be breakthrough attacks that are frightening for the patient and may erode his hope. Hope for recovery -- which is definitely possible with panic -- can be a tenuous but very important thing. Best wishes.
