Flatline

My experience is to have a small flatline around the first week mark and then had a larger flatline around 3 weeks in.

 

Hii Brother. Flatline means your brain is setting the dopamine levels to normal level so it's a sign that you are healing from this addiction. it will come again and agian till the time your dopamine are normal.

 

Flatline brings all of these symptoms bro

 

For myself i found i would get random spells of 3-4 days with low libido along side 3-4 days were my libido returned and this just continued to go around in cycles so i'd say all is perfectly normal!

I would say you are focusing to much on when your libdo is low and allowing your head to talk yourself around to fapping to check yourself. When on NoFap prepare yourself mentally for feeling both these stages.
24 hour access porn has created the idea inside us we all should be feeling like sex 24/7, that's not how reality works. Reality is feeling your libido high sometimes others not, but if you meet a girl for your libido will instantly change to high mode so don't be worried about that.

Think about it logically if we we designed to constantly have a 24/7 high libdo we would get nothing done. In nature some animals have evolved to think about nothing but sex, When they mature they stop eating and do nothing but mate till they drop dead from exhaustion.
