Yikes. I don't go anywhere without my Nalgene bottle, usually filled with water or iced tea. It appears I've been slowly poisoning myself, for years now.
Fortunately, there are alternatives available. Nalgene also makes bottles out of non-Lexan plastic, or you can skip those entirely and find a retailer of stainless steel bottles. (Can a bottle be made of steel? Does bottle denote shape, or material?) I'll be going for the stainless steel variety, for now.
