Soda is killing me

Lately I've been really cracking down on my soda consumption. I need to plan ahead and take special drinks because everyone else is going to be guzzling alchohol or cola and if I don't plan ahead I'll have limited options to have a healthy drink. I find my resolve disappears halfway through Sat. on those weekend events on a hot spring day. Then I will grab any soda someone offers me. It's not their fault. I have to learn to say no thank you.
