Understand here what you are really doing. You aren't giving up pop. You are giving up SUGAR and that is a for real addiction. It might take you a number of tries but don't give up. Maybe try next when you can arrange 4 days off..so a 3 day holiday weekend and add in a personal day so you can be home. 3 to 4 days really should see you over the hump.
Caffeine, in moderation, is just fine.
I think that only applies to the "Southern Style Sweet Tea" that you find in the homes of many southerners, along with some restaurants that have bowed down to the "fad" of Tea that is so sweet it has the consistency of syrup.
We used to have sweet tea at home when I was a kid; it was NEVER that sweet, I have no idea where that crap came from except people that just didn't care about their health wanting more and more and more sweetness (like my wife).
Personally, I like unsweet. I've never completely given up sugar, pop, etc, but a few years ago I decided I was going to be more mindful of those things. I drink pop maybe once a week now. The things I drink is order of what I drink the most: water, beer, tea and in the order of what I actually prefer the most: beer, tea, water. I'm just too lazy to make the tea; I can easily drink a couple gallons a week if I'm not feeling like water and I'm trying to watch my beer intake.

True. BTW I just finished a trial involving a fatal hemorhage following anticoagulation for atrial fib. Good guys (healthcare providers) won.
