Comment with one of your worst dopamine hijackers; something which takes over and hogs your dopamine system, and on New Years Day I'll go through the comments and rank the top ten on how many upvotes they get and edit this post with the results as well as make a new post. Maybe even make a New Years Resolution based on it!

If there are any duplicates only the one with the most upvotes will be counted. Any comments/replies which are chat or reactions will obviously be disregarded from the final count.
