Hello there and welcome!

Today is day four for me. Some of the things I bought (in addition to what our one and only MusicalMomma listed) include:
-Diet Ginger Ale, Diet Black Cherry Vanilla Coke, Diet Pepsi w. Lime
-Lots of vegetables and greens (scallions, mushrooms, tomatoes, broccoli, asparagus, green leaf lettuce, peppers
-Can't Belive It's Not Butter Spray (the herb and garlic kind)
-Sugar Free JellO (both ready made cups and the make at home kind)
-Lots of chicken and a big bag of talapia (I don't eat red meat so I stocked up big time on fish and chicken)
-Crystal Light to go packets (they really help for chugging down the 64+ ounces of water a day)
I plan to buy some of the DaVinci syrups soon. I'm still in the process of hunting for a bargain...
I think one of the biggest surprises for me so far...

I have only had one soda in the first 3.5 days. Shocking! I've always drank diet soda and would usually have 2-3 a day....which is kind of why I wanted to make sure I had variety because I figured it would help get me through the rough patches. Surprsingly, I haven't even really felt like drinking it. Progress perhaps?

Who knows, but I found it to be an interesting observation.
Good luck as you start your journey!
