I honestly think his pride will be wounded either way. He is a leader and someone that people have looked up to, and in a sense he feels that he is expected to be "better" than normal. So for him to "give in" to his urges, I think would be a very traumatic experience for him. I did consider allowing it to happen as he slept, or in subconscious daze, and I like that the same idea came to you independently, so I'll definitely include that.
Alright, so the first one is going to take 10-12 days, but gradually his own willpower will begin breaking down and the time intervals will get shorter. We can timeskip through some of it though.
