Valium/dental work update

I ended up taking 2 valiums before my appointment (10mg total) it helped calm me down but i didnt go to sleep at all. I got through the needles & let the dentist know before hand that i have a high tolerance for lidocaine so it takes a while to get me numb. He went in around 10 different times to get me fully numb. Extracted what was left of the tooth out of my gums & then xrayed. To make sure it was all gone then filled it in with cadaver bone graft. I wasn't in pain, i didnt cry or panic which is great due to my extreme phobia of the dentist. I'm recovering now & have to go back in a week the remove the stitches. Thank you ladies for your help & advice.
