Thank you.
Perhaps I can ask Mr. Passey a quick question. You talked about nightmare Fridays. Dr. Ritchie mentioned nightmare Mondays, or something akin to that. I'm sorry if this is a dumb question, but is that simply because if you're taking the drug once a week, it's on the day you take it that you have really bad nightmares? Is it only on that day, or are there other effects throughout the week too?
