Struggling. Please help

I have seen a lot of ups and down in this journey. I have started this journey in Aug 2016. First i went 60 days hardmode n during that i started getting morning woods. But after that I had sex n went into deep flatline and lost morningwood. I continue the journey amd after 80 day mark i got morning wood back 100% erect. Around 100 day i wake up n felt very different, penis shrinkage n all. Now i am almost at 120 day of no PMO but my morning wood has not came back. This non linear progress is very frustrating. I have O relapses, limited internet use. I also feel non linear progress in my Libido. Please help

Have you not consider having nocturnal erections instead?
I just had 3 morning woods straight in the row for the first time since I remember. But I use to wake up in the middle of the night with one almost every night. Just changed my sleeping habits and MW is back. Maybe you are sleeping right through them?
Also when I got really anxious I would wake up in the night with limp dick too, so this might be a reason worth considering.
Cannot tell much about non linear progress cause I just started hardmode, before I would just avoid porn and reduce masturbation. But from what I read it's normal to feel this way, and those things resolve itself on its own.

you are 120 days clean, no relapses and you are experiencing a PROGRESS like you said. if it is non linear, so what? it is well known by now that progress is non linear so it is 100% normal for you to experience it like that.

120 days clean and progressing, what you need help with? you are doing excellent, just like any successful rebooter does.
