I would love to do this, but I don't think I can. The main purpose of my participation would be to lessen my caffeine intake since I think that is my biggest problem that can be solved conventionally and with some immediacy. My addictions are getting better already somewhat by necessity - much less soda since I can't really afford it and more water with caffeinated flavor packets - but ideally I would not need the packets at all. It's a slow battle. Going cold turkey has always failed me in the past and will continue to if I try again. Cutting something like that out entirely is doable of course but for me it only exacerbates the feelings I use my addiction to cope with. I'm not going to immediately learn alternatives for my methods, and until I do (as my most ideal self would) half and half is good enough for me right now. It's a lot better than 100-0, which is how it used to be. I appreciate the intent and support the movement. I think there are a lot more variables aside from self-induced complacency that stop us from being better, and some of them are more difficult than others to throw aside for a weekend. That is not an excuse! I decided today at work that I would try to schedule myself some simple self-workouts also, so I guess I'm kinda doing this challenge in my own half-baked way!
