Day 1 went okay. I felt a little tired and decidedly cranky in the evening, but once I had dinner, things felt much better.
Dinner itself was fabulous. We made spaghetti, using spaghetti squash in place of pasta and making a sauce dense with vegetables. It worked out really well... I have a feeling that squash may become a centerpiece of many entrees during this cleanse.
Most people struggle with any kind of special diet because of the sense of deprivation. There tends to be a lot of remorse around what you "can't" have, and often giving in to the temptation of eating what you aren't supposed to is the end of a healthy diet. I wasn't feeling this much at all though, which surprised me. Perhaps it's a little early into the process, but I haven't had any real sense of "oh, I'm going to miss _____."
I did some introspection about this, and realized that it's because I am so excited about what I am going to get. When I left work, I was speculating on what I could cook, wondering what I could be creative with to make a tasty, satisfying meal.
When trying to be self-disciplined about anything, the key is to focus on what you do get to have, rather than worrying about what you don't. Which really goes back to having gratitude - being grateful for what we have, rather than remorseful about what we lack.
