NoFap and Less Sleep, I need some reassurance

Hi
I am pretty new to this forum, and NoFap, but I have been really trying to quit PMO. The last two times I tried to do it, I got to 5 days, the 3rd time I tried I got to 9 days, which is the longest streak for me, and I want to beat it and get to 365 days.

Theres is really one thing that is only holding me back from advancing, and that is the sleep aspect when I get to day 5. When I got to my 9 day streak a few weeks ago, I didn't think much of it, and I didn't realize this was going to happen to me, and in my head, I felt I was going crazy (figuratively) because I am obsessive about my sleep and have been since an I went through an awful withdrawal last year where I had a bout of insomnia for 2 nights. I was able to fix that because I take medication for sleep and I have really bad anxiety and I take medication for that as well.

What is bothering me is that I am going from 8 hours which I usually get with PMO, and then I was going down to 5-6 hours at night. I wouldn't exactly feel groggy per say, but I was worried about this. What I would do is go to bed at 11 and wake up around 4 or 5 and then I would lay in bed and try to nap off, but I wouldn't have any dreams, I would just wake up at 7 and I wasn't sure if I was just laying there or if I was sleeping.

I really am in need of assurance, because I am going to try this again. Has anyone here had the same issue? has anyone had sleep change since NoFap or when they were rebooting and if so, did this change?
