My church recently did what they call a 40-day fast. We still eat food, but we collectively decide to give up tons of shit and replace it with churchy shit.

For instance, I stopped listening to death metal about sexism or self-harm (Asking Alexandria) and started listening to death metal about searching for truth and love (Protest The Hero and Killswitch Engage). I also stopped eating fast food. Instead, I cooked for myself. I even gave up Reddit and other social media for awhile so I could do more productive stuff like art or homework.

You wouldn't believe what 40 days can do to your life if you can replace annoying habits with awesome ones. I actually dislike eating out now. I wouldn't say it tastes different, it just doesn't seem appealing having to drive out and pay ridiculous amounts for food I can make on my own. Reddit (and my smartphone in general) have become less appealing to me as I've replaced my habit of checking into social media with more fun projects.

I'm not saying you should do a Starbucks fast, but I do want to encourage you to look farther than you can see if you're trying to stop. The first couple of days of trying to change yourself seem futile, but a full month can make a big difference in how you feel. I messed up the fast I did everyday for the first week or so, but I kept going with it. It isn't important that you mess up, it's important that you always look to improve where you can.

I would suggest replacing your Starbucks drives with home brewed experiments. Get different flavors, creamers, and toppings and try out new things. It'll probably be cheaper to make it yourself, and probably more fun.

Also, when you do go to Starbucks, try to very slowly reduce what you order. The first month, stop adding whipped topping. The second month, forget about one of the flavors. The third month, do half the sugar. The seventh month, stop ordering fraps. The twelfth month, stop ordering coffee altogether.
