When at an (evening) party Dr. Krane and Dr. Briggs agree to meet the next morning 09:00. In the next scene Dr. Briggs is researching Dr. Krane's past in a library, its busy and obviously early in the afternoon. After that scene, she arrives at her office where Dr. Krane is awaiting his appointment.
The memories from someone else would be seen in the first person (their point of view), not the third person (outside observer).
During the flashback of Gleick's interview of Krane, he says that Krane's blood alcohol level was "2.5". He most likely meant .25, or just over three times the limit deemed legally impaired (in most places). For Krane to have been at 2.5, he would have been five times over what is most likely a fatal amount.
The first time injecting the memory serum on himself, Dr. Krane inserts the needle in his arm in the wrong direction; against the flow of blood in his body. Any medical professional knows venous injections are only given in the same direction as blood return to the heart.
When Bressler set the fire in David's house, he used a small jar of rubber cement, While it has some volatile and flammable properties, it would have never burst into flames like that.
