I drink a lot of tea in the winter. I drink my two cups of coffee in the morning and then the rest of my day is caffeine free usually. I am pretty sensitive to caffeine and if I drink any after lunch time it adversely affect my sleep that night. I really love my sleep so I have learned to avoid it after mornings.
Caffeinated tea has the delightful effect of making me very very nauseated if I drink it hot, for some reason iced tea is fine, but hot caffeinated tea makes me want to vomit. Not sure why, so I avoid it, plus it has caffeine so I would avoid it after lunch anyway.
What I so really love when the weather is chilly in the afternoon and evenings is herbal tea and I think Celestial Seasonings makes the very best herbal teas. I think orange and mint teas are my favorite. I recently found Mint Magic and drink it by the gallon. This time of year they also have the holiday teas out the Gingerbread Spice with a little honey is pretty heavenly.
Are you a tea drinker? Black, green, white, red, or herbal? I can drink a little green or white tea but mostly just avoid the caffeinated versions.
