This resonates with me. When I tried Soylent, it was because I was working WAY too much, and that "always-on" mindset carried over into other parts of my life. I felt like I didn't have time for food - I needed to be productive instead! Soylent markets to this extremely well, and it worked on me.
I stopped using Soylent when I found a healthier work/life balance, started meditating regularly, did a bit of traveling, started exercising more often, and met a new love interest. I wouldn't say that I'm a stellar cook, but I enjoy preparing meals - it's just another thing to try to do well.
So Soylent isn't really for me - though there probably are some lifestyles in which it makes sense.
