Why is this streak different from my last?

I’ll just cut to chase, basically I’ve reached 90 days recently and that’s great and all, especially because I’ve never managed to before. The only thing is I believe I’m still in a flatline and I haven’t fully recovered my morning wood. Now the reason why I’m frustrated about this is due to the fact that back in late 2018, early 2019 I managed to do a 70 streak which was my longest at the time. During that streak I was out of the flatline, my depression was COMPLETELY gone, and I was getting rock hard morning wood.

I believe you can see where I’m going with this. How come on that 70 streak I did long ago I made more progress than on my current 90 day streak that I’m doing now?

The only difference between the two streaks would be I did look at lewd images around day 40ish, but it’s been close to 2 months since that and I’ve been clean the rest of the streak.

If someone got an explanation, that would be very appreciated as I woke up very groggy this morning and being frustrated with this isn’t helping.
