In 2 weeks I'm having all of my teeth removed. I'm only 25, and have been severely neglecting them. The dentist said he could save about 2/3rds of my teeth but it would be way more expensive than I can afford so I decided I wanted them all removed. I won't be put to sleep because I can't afford the cost. I know I'm going to freak out because just thinking about it I get shaky and nausiated, and it's still 2 weeks away. He said he would give me Valium to take the day before and day of, but I've never taken it, and am worried that it won't be enough to calm me. Any tips/suggestions?
