I get saline twice a week and I get 2 liters. It takes 3 hours each day. The first time I got it, I only got 1 liter and I felt absolutely amazing. The next few times it wasn't as good but I still got benefits from it. After 3 times with 1 liter, I went up to 2 and that seemed to help much more. I don't get palpations as much, not as much dizziness and I always have more energy after. While you are getting it, if you do the 3 hours, you get very tired but afterwards you feel a lot better. I really enjoy getting it plus there are 2 other girls who are there around my age with pots, so that helps. Hope this is helpful
