Is a silicone tube safe to use as a straw to drink water from daily? Everywhere I've read says non-liquid silicone is safe and non-toxic but the websites that I saw were mostly talking about using it as a container which is a little different because you're not putting it in your mouth and probably not using it daily.

Before you ask why I'm doing this, it's because I want to make sure I drink enough water everyday but I can't be bothered to constantly refilling or picking up a 2L bottle everytime I take a drink.
