briefly when I was getting a shot at the doctor, years ago... And once (previous to my most recent visit) at ABHS, on day 3 of my detox, because one of the medications (that ironically was supposed to help with the stomach issues that come with withdrawals) they were giving me was making me throw everything up (even water) so I got to the point where I would faint when I was standing up and had to leave the detox to visit the hospital. Once I had gotten an IV of fluids and potassium, I was totally fine, but the hospital did inform me that I had such a low amount of potassium and water in my body that I could have had a heart attack! So, that part was a bit concerning...
