Today I have almost used Sleep cycle for 2 months and it really gave me a new light on my sleep and how it affects me. The past days I have been so tired and without energy and I can see in the app that it is because I did stupid things to my sleep like going to be at random times and not just jumping out of bed at a certain time. I do not have much else to say other than I highly recommend it or some way else of measure your sleep as it is truly a superpower to get a good sleep. I cannot wait for my new bed to arrive next Wednesday so I can get a new start on my sleep.
