I can recommend leechblock a lot. It allows you to block websites using Regex and some time based rules. You could for example block reddit from 0800 to 1900 but still open individual posts you found while using a search engine. For me (I have ADHD, but I don't think that makes the difference in this case) that's the perfect balance between usability and avoiding endless scrolling.
