I think going cold turkey is not a good option for you because it's not a easy thing to get off something that has been a habit for a decade. My advice would be everytime you feel like jacking off, just have a go without porn. It'll be hard but just do it and make yourself used to getting off at a normal dopamine level. Slowly go down on the number of times you fap in a day and try improving that number. It's a mental battle, because this is the technique that is working for me. I have reduced my number from once everyday with porn to 3 times a week without porn with my phone beside me. I am not at the level to go months without beating off but maybe in a month I will be ready to go on a streak without torturing myself. Everyone has their own way but this is what's working for me.
