I have kind of a weird question. Water from our faucet tastes strange, so after my daily trip to the gym I bring home some (filtered) water from the fountain in my bottle to drink later. But later it always ends up tasting/smelling so strange! Not just strange, terrible! And it gave me a terrible stomach ache the other day when I drank some of it. When I first put the water in the bottle for when I'm exercising it tastes fine, but when I save water in it to drink later on it ends up taking on a terrible, chemical smell...can't think of a better way to describe it really. It's just an ordinary plastic water bottle,the kind made to put in a bike bottle holder. I have heard about chemicals from plastic water bottles leaking into the water, but I thought that was only with bottled water, not reusable bottles. I mean obviously I'm going to find another water bottle from now on but if someone has some insight about what is going on I'd appreciate it.
