I found out today after reading the potential problems from drinking too much water can do to your meds, but also it takes away your sodium and potassium levels too. When I was in the hospital i had to take a large quantity of two pills to replenish my potassium, but they never said why. I always thought drinking water was healthy and never realized you could have so much problems from drinking tooo much. Go figure, even what's good for you is sometimes too much.
