Any known major issues with Splenda? I do try to avoid all artificial sweeteners (not sure how good it is to trick one's body into thinking it's consuming massive amounts of calories when it's not), but I do drink it in tea with some regularity and very occasionally coffee (have tried to train myself to unsweetened, and it hasn't worked). Otherwise, it's water except for the maybe once a month small glass of fruit juice or an occasional small glass of soy milk if I'm running out of the house without breakfast.
