Less sleep

Hello everybody. It is pleasure to write to you. So. I have been doing NoFap for a long time. Currently I am in a 42 days of complete semen retention and I am up at 2.30 at the morning to read and be here with you in this forum. I said long cause the whole summer was NoFap for me, but wasn't practising retention back then and last 2 years I am doing fine. So... In the summer my sleep quota dropped significantly . I was getting up at 5.30 am. at 6am. Actually It was really hard getting up after 7am. There was that day in 4 am I was out doing pushups like crazy cause I could not sleep and got nothing better to do. So here I am at the current moment. I woke up 2.30am even though I had to travel 500km the previous day to see a doctor. Please give me information. Is that sleep dropping due to transmutation? Let me know what you think about NoFap and sleep in general.
