There are half way houses in your town for tea addiction. I suggest switching to other forms of liquids for now like coffee. But do it quickly as Starbucks is clsoing 600 stores and converting them to halfway houses for tea addicts such as yourself
I've been visiting a Greek restaurant in Birmingham for years when I travel there for work. They serve Mint Tea which is very delicious. I think they make it with a combination of mint and regular tea leaves, since it looks like regular tea but tastes like mint.
MY suggestion here, would be, a "Berries mix with Pepermint".
Put dried berries + pepermint in a pot, let it steep, cool it down, put in the fridge for a while & VOILA! - A VERY TASTY DRINK DURING THE HOT DAYS...
(No need for sugar.)
Do you ever watch those 3 doctors on TV in the middle of the day? They were saying peppermint has the ability to deaden the nurves in your throat for a while so it is excellent for caugh. I tried it and it works great.
