One thing that caught my eye was a set of popsicle molds. We used to have these when I was a kid, and I thought it would be fun to experiment with a few homemade flavors again.

Idea: Everyone gets to taste each flavor and rank them from best to worst.

The flavors:

  • Orange juice
  • Apple Purée with a hint of Lemon
  • Kiwi
  • Cola
  • Aquarius
  • 0.0% Beer

The results:

1 – Gold! Aquarius Aquarius Orange
2 – Silver Orange Orange Aquarius
3 – Bronze Apple Cola Cola
4 Cola Apple Apple
5 Kiwi Kiwi Beer
6 – Last Beer Beer Kiwi

Alan and Alex came up with some great ideas: a coffee popsicle for me, a vanilla yogurt popsicle, a stracciatella-flavored yogurt popsicle, and a chocolate milk popsicle. That will be our next experiment.

Instead of four or five, I now limit myself to just one. After my 0.0 month, the effect of a single cup of coffee is now very noticeable. After just a few minutes it kicks in: my senses become a bit sharper. I see better, I hear better, my thoughts are clearer. It lasts for a couple of hours, during which I slowly return to normal again. This will probably only last a few days, and then I’ll be used to the caffeine boost again. Still, I’m going to try to stick to one cup a day.

The other part of my 0.0 adventure was alcohol, and I actually didn’t notice anything there. Since I don’t drink during the week anyway, and only have drinks on weekends when we’re with friends, I’m going back to my habits before I started the test. A few beers on the weekend, and that’s it.

Conclusion: The only clearly noticeable thing was reducing my coffee intake. The adjustment regarding alcohol was quite easy. I did enjoy the experiment, so I might do another April 0.0 next year.

Normally I only have a few beers during the weekend, so I don’t expect this dry month to be very difficult. I just wanted to try it and see if I notice anything.

To make it more likely that I notice something, I’m adding an extra challenge to this experiment: no coffee. On weekdays I usually drink about four cups a day, so together with the no-alcohol rule this will make for a bit more challenging month. I’m curious to see what the effect will be, and if I even notice anything.

The experiment still seems fairly simple, even with the no-coffee rule, so I’m adding one more twist. I’m going to do it secretly. Not in the sense of hiding anything, but simply by not announcing that I’m spending a month without alcohol and coffee. I’m curious to see if anyone in my family notices.
