A glass of diet Dr. Pepper when I first get up, then flavored water the rest of the day. I do take it with me to my sewing room, but I sit the glass faaaar away from where I'm working. So far, so good. :)
I occasionally have a rum-and-diet soda right before going to bed (it puts me right to sleep - what a "party animal" I am! LOL!), but I don't drink it while sewing. That's an accident waiting to happen! :shock:
