How to manage after Ayurvedic treatment and excessive masturbation?

Hi doctor,

I am an 18-year-old male. I masturbated for the first time when I was 12, and I continued it daily. I was aware that this is harmful, so I stopped and started restricting myself, but I was unable to do so. However, I made a change and started doing it once a week. Three years ago, I used an ayurvedic medicine, which is used for nightfall. I think it decreases chemicals in my brain because my penis was not erecting during the medicinal period. I used it for one month, and this helped me to stop masturbation. But now a new problem occurred, nightfall which was not so big. By thinking "do not dream too much" I decrease the frequency of nightfall. But now here is a big problem and my real issue starts. I am doing masturbation while I am sleeping for the last three to four months. While I am sleeping I do not know how, but I become partially awake and do it. I do not think anything at that time. I cannot do anything, but I just wake up, masturbate, and sleep again. Even sometimes, it was becoming so worse as I am doing it below a pillow or with a bedsheet, and my penis got some minor damage like scratches, etc. Then I tried a new thing, I started to tie my hands with a rope so that my hands cannot reach my penis. I tried many things, like tying my hands and legs also, but I masturbate by sleeping upside down. Now I am frustrated. What should I do? If possible then please solve it here. Somehow if I reached out to a doctor then how he will treat it?
