A few questions

Hi guys
A few questions really.

I decided to start nofap at the start of November 2018 after hearing about all the no nut november stuff.
I started PMO probably when I was around 14. However, having read through the other threads my addiction doesn't seem as bad. I'd do it probably around 4 times a week, maybe 5, I'd never do it more than once in a day.
My first streak was around 21 days and I didn't feel any huge benefits. To this day it's my longest streak, simply because I guess I kind of got disillusioned with nofap, thinking either it didn't work or I wasn't as badly addicted as I thought. I've decided to start again and do a longer streak.

I'm just wondering if, because I was not as severely addicted;
- Will it take me longer to experience benefits?
- If I do start to feel different will I get a "flatline", and if so, will it be less severe than some of the others I've heard about (e.g flu symptoms, depression, erectile dysfunction etc...)

Thanks a lot guys.
I've been following the forum for a while but this is the first time I've posted. It's nice to be in a community of other people with the same problem.
