I'm someone who usually runs on caffeine, but I tried to use the hot lemon water as a substitute for the energy drink I usually drink every single morning.
At first, I failed. There's just something about carbonation before 9 a.m. that my body craves.
But about 10 days in, I finally got to the point where I was not consuming caffeine of any sort until early afternoon, which was huge for me.
By day 25, I found myself less reliant on caffeine altogether and simply drinking more water — often lemon water — throughout the day.
I'm not totally caffeine-free after my experiment, but I am less chemically-caffeinated than I was 30 days ago.
