Fortunately, my trial coordinator has given us a
dosing diary which I would never under ordinary circumstances use but now, will absolutely not do without. I can become very distracted if I have a lot on my mind and sometimes I forget whether I have taken or not taken a pill even immediately afterward. This is how the dosing diary works. There is a column for Day number, column for date, column for time, column for drug, column for 2nd drug etc.
