Water mostly. Room temp---cold hurts my teeth---and from the RO water dispenser at the grocery store. The tap water here tastes weird and regular filters like Britta dont help the taste. I have either coffee or an energy shot (like 5-hour Energy but store brand) every morning. The energy shots taste terrible but some days I don't feel like making coffee and at least they go down quickly. I do like grapefruit La Croix and Bai coconut drinks. And homemade sweet iced tea, made outside as sun tea in the summer. Although I haven't made any in the past few months. Well, it was a weird season; on the news they said it rained 43% of the days this summer! So I guess there weren't many good days to make sun tea and that's probably why I didn't think of it at the time. Other than that there aren't a lot of flavored drinks I like.
