I drank my last can of Citrus Drop to get going on Thursday morning and haven't bought a new case yet. If I make it through tomorrow it will be a full week. Admittedly, I had some root beer on Monday and last night I had a 7-up, but my main weakness is the caffeinated sugar water.
I have an early meeting on Friday, so I won't be upset if I have caffeine that day. Of course, if I don’t have any soda in the house, I won't be very likely to drink it, since most of my consumption happens in the morning while getting ready to face the day.
