Biphasic: Day 36.1

I was very tired last night. It was the first time I had difficulties staying up to 2am in a very long time. And yet, I couldn't get immediately to sleep either. I gave myself plenty of extra time to fall asleep, but I fear that I may have gotten up i the middle of a cycle... I feel extremely tired and thoroughly exhausted this morning. I'm debating sleeping for another cycle, or adding another cycle to my core temporarily. I'm not sure what to do. If I do give myself an extra cycle and find that it wasn't a 4th daily cycle I needed but to fully complete my 3rd cycle, I would have changed the experiment in vain. And it might be difficult to switch back if needed. I'll be keeping track of today more closely than I normally would.

I was hoping this kind of exhaustion and tiredness wouldn't happen. Biphasic sleep would be such a wonderful thing if it would work with my life, but I won't force anything on my body that I know is detrimental.
