So I saw the dentist finally after avoiding them for like 5 years. Well they said I needed a root canal and perhaps more than one, plus I have alot of little cavities. When I went, I fell apart and barely made it through the basic xrays and cleaning, so she gave me Valium 10mg to take before the root canal. What is the Valium going to make me feel like? I'm so anxious about the root canal that I need assurance that I will be so out of it I don't care what's going on.
