During ED brought on by diet coke and take out addiction?

Im crazy and I have ED at 24. I have a diet coke addiction and a take put addiction. That's all I consume. I'm sure that that's the source of my ED. Do you have any suggestions food wise and drink wise to cure my erectile dysfunction? Should i just drink water? Are there things I should be eating?

I think that you may already know your answer. You might want to see your primary physician for a referral to a vascular specialist for blood circulation and/or a neurologist for possible nerve issues.
That diet certainly isn't doing your body any favors. Aspartame hurts some people badly.
High-salt, high-fat, high-artificial sweetener and high-carb diets may be tolerated less as you get older. Eat some real food. Water is always good.
In order to change your diet might require a significant lifestyle change.
Best of luck to you.
