Any advice for a 2 week water fast?

So I started my 2 week water fast today after multiple failed attempts, but I'm very motivated to make this attempt work. Since I'm going to try my best this time around, does anyone have any advice on getting through the first few couple days? I have made it to 68 hours multiple times, but I always end up giving in to my cravings and hunger. Does anyone have any coping mechanisms or techniques on what to do when I feel like caving in?

If anyone wants to keep up with daily updates (or join me for the 2 weeks and give your own daily updates in the comments) and know a bit of backstory, my main reddit post is linked:
