I'm like a fine-tuned race car. You've got to make frequent pit stops when you drink as much tea as I do.
People don't realize where unsweet tea came from. During the war they had to ration sugar, so then everybody just had to drink bitter tea, or unsweet.
Ice will ruin the tea. Waters it down. You can always get ice, or carry your ice in an ice container. You don't want to put it in your tea, it'll water it down.
