When to expect morning erections to return

Hi guys,
I’m 4 days into PM and my penis has been lifeless since. I feel like I’ve hit a flatline from day 1 (is that normal?). My libido is non existent and the thought of looking at porn or thinking about any sexual fantasies simply does not interest me at this point in time.

I’m 23 years old and have been masturbating since I was 11. Although, I started watching porn when I was 14 and had masturbated multiple times a day (usually twice at minimum). I almost always used porn to masturbate to during this time and have found myself gradually growing a tolerace to the stuff that I liked. However, I never became interested in heavier material; mostly just the same content but different videos each time.

Over the last year, I have been experiencing erectile dysfunction. I’ve been with a few sexual partners over the space of a year (since my last relationship) and have experienced ED with almost every one of them at least once. I have managed to have sex with them though after multiple attempts on different occasions.

The fact that I have had no erections since starting nofap has freaked me out a bit as well as experiencing what seems to be a flatline. How long should I expect to wait until my morning erections return as well as my libido?
