We no longer make tea at home. We only go out to eat a few times a year, we order tea then, most always unsweet. I have drank diet soda for about 35-40 yr.s, maybe 3-4 per week. 2 big cups of coffee a day, no sugar, no cream or milk.
When kids were still at home I use make Sun Tea, put water in a gallon jar w/4-5 tea bags, set outside in the sun until as dark as I wanted it, sweetened w/about 1/4 cup sugar,last kid left home 24 yr.s ago.
