I am really into drinking a lot of water, and I am trying to get 90% of my calories from whole foods, and I never add salt to anything I cook. So, I am not really taking in a lot of sodium, and I am taking in around 160-180 oz of water/herbal tea a day. I seem to be thirsty a lot, so I would drink more, but I can't spend my entire life in the bathroom. I'm also putting in some hard gym days (often an hour or more of lifting three times a week, mixed with HIIT on alternating days - always resulting in soaked work-out clothes), and it's just plain hot in the Midwest, so I'm also sweating a lot.
Should I worry about electrolyte replacement? If so, does anyone have any recommendations for electrolyte sources that are inexpensive and not full of either sugar or artificial sweetener? I'd like to try coconut water, but the only time I've seen it on shelves, it was $4 for a 20-oz. bottle. Not in my price range.
