How to control urges after flatline?

Im 60 days in nofap, i had strong urges to fap and PMO in first 2 weeks and then I hit the flatline, and I was in flatline till last week.

But now, my libido is back with a bang, and I feel myself unable to control myself and I have to touch my penis and I will be honest that i edge a bit too, but even then the urges dont go down.

Its like i will have a heart attack if I dont act on these super strong urges , any suggestions?
And also, when will these urges go down and I will be able to control my libido and have a stable peaceful state of mind?

 

I know and I have made it a point that this is a battle in itself of not touching your penis.
No matter what happens, i will never touch my penis at all. Im taking cold showers but still when I sit down for my project , i start thinking about sex and then i have an erection and then the urges become uncontrollable.
When i sit on my chair for my project, and sexual thoughts come in my mind, what should i do then?
Slap myself on face to remind that these thoughts should not come or pinch on the hand that will force the brain to associate feelings of sexual thoughts with pain or something else?
