It looks as if he really is seeing something in the first one that he is trying to get. I'm saying this because he does the air snap, then he looks to the floor. Keep recording them....it will take some time, but eventually you will get on video what you need to show his Dr.
The Dr would probably do the phenobarbital first. Phenobarbital is a barbiturate and diazepam is a benzodiazepine. The phenobarb is longer acting. We use diazepam to supplement his phenobarbital.
