Flavored water bottle is not hard to DIY. Keep brewing and drinking tea in the same bottle and never wash the lid (I use Thermos, you know the lid if you know). Now the lid will get a nature tea flavor and even with plain water, you can smell the tea flavor and feel pleasent when you don't get any caffine.

I shared this DIY method with my friend. He said it's not DIY, but lazy and dirty.
I insist that it is a natural process and a life hack to improve life quality.

Yeah, I'm lazy.
