Biphasic: Day 38-39 or not

So this is a strange. The last two nights I decided to give myself more sleep than usual to prepare for and recover from the big luau. While I did feel well rested and energetic yesterday evening despite not having my nap, I considerably overslept this morning, causing me to be late for work. I've noticed the only time I oversleep or something bad happens with my sleep pattern is when I change it, even when it seems like a good change that would make me feel more well rested. So I am going to continue the biphasic pattern, but no more leeway. I will give myself one more week of 3 nightly cycles, but after that I will return to 2 nightly cycles and it will stay that way. I will wake up every single day at 5:15am like I did before. The consistency will make my sleep pattern routine once again, and I'll be back in the game.
