Drinking more water? Dizzy/hot flash spells...

Kingston54

I was at the doctor today and told him how I had two dizzy/hot flash spells in the past week and he said it sounds like I'm experiencing dehydration.  He asked what color my urine was (light yellow) and said it really needs to run clear so I need to up my fluids.

Here I thought I was getting enough, but apparently I'm not.  I forget the ratio - isn't it based on your body weight?

Just wondering what your thoughts are on how much water should be consumed. Also, has anyone had the dizzy/hot flash spells and solved it by drinking more?
