Hi, for the last couple of years I m never thirsty! I never, I mean never drink water. Every morning I have a cup of coffee that takes me couple hours to finish { warming it up a lot} I can eat all meals and don t feel the need to drink anything, I usually don t. I d say the last 2 years I have been having tightness in my chest { I have Asthma} I feel like I m having a heart attack on top of that I get dizzy standing up, light headed and headaches. Is this because I m never thirsty, so I don t drink anything?
