I've never considered myself myself to be someone who was dependent on caffeine but I do work at Starbucks so there's a lot of coffee in my house so I got in the habit of having at least one cup of coffee every day. A few weeks ago I was having trouble falling asleep so I decided to quit caffeine cold-turkey to see if that would help.
The first day hit me way harder than I thought it would. I had headaches and I fell asleep for over an hour on the couch in the middle of the day. The morning of day two I was already rationalizing with myself that it would be totally fine if I had just one cup of coffee; it was cold out and I was craving it.
I managed to hold off and only caught myself staring longingly at my coffee maker once and I did notice some changes. The first day post-caffeine break I cherished that morning cup of coffee that I'd been counting down the days to but after that first day I've noticed that I no longer feel like I have to have it every day. Some days, in fact, I even forget to turn on the coffee pot! I don't think I could ever be completely caffeine free, I like my coffees and teas too much, but I did not miss the caffeine crash in the afternoon. Now that I've significantly cut down how much caffeine I'm taking in my head feels clearer, I get more sleep, and because I get more sleep it's easier to wake up in the morning. If you've got a coffee habit like I did I strongly suggest taking a caffeine vacation, even for just a few days, you just might feel better afterwards.
