It can be done. It is possible. Living out of a hotel for 3 days relying on restaurants or other catered food that I have no control over is not an optimal situation. My plan was to be optimistic that there would always be something available to me. If a meal situation came up where there were no options for me, I would pass and find something on my own at a later time. Luckily for me, none of those situations presented themselves.
Like I said before, things are different this time. Making the correct choices has become second nature. I don't even notice what I'm "missing" anymore. This is just the way I eat. Meat, vegetables, some fruit, nuts, and that is it.
