Hi. i'm so anxious and need advice and anyone who would share about their experiences with medications taken during dental and medical procedures. i have to have both this month

It's so hard for me. We're a mess anyways and any input about what is good would help so much.
The dentist mentioned a benzo - 'tradazone' or some thing that sounds like that. Anyone have to have sedation of a dental surgery recently.
Thanks so much,
kerria
