What if you started out slow by replacing the sugar in your sweet tea w/ sugar substitute??? But, then again, if you think you can go cold turkey I guess that's not really a good suggestion. LOL
I used to drink Pepsi like it was going out of style, but I gave it up when I started Southbeach. I do drink sweet tea, though, but I use Splenda instead of sugar. Being a born and bread Southerner, it was tough for me in the beginning...but now I'm used to it. Next step is going to just water, Propel, and flavor packets...but I'm not ready for that just yet.
