On the upside of the whole trying to change for the better. I have cut out most of my caffeine. Though I still do consume it. And I still have the occasional soda. It try to limit it to one serving at a sitting. And I do try to avoid it in general, as I do most things.
Lack of caffeine is making me sluggish but I'm sure that will adjust. I'm drinking Green Tea to help compensate for the lack of soda. It's not diet but it's 100 calories per bottle instead of the 130 per cup I beleive Dr Pepper is. Tho I still crave it. It is a big weakness, though I won't stop drinking it completely because if I do then I'm more or less just going to break down and start drinking it all the time again.
I lost 2 lbs last week. Pretty sure that is mostly water weight from cutting back on the soda.
