I am losing my voice in the last 6 hours. The last two days have had a stomach bug, no vomiting just diahrea. I have been very tired. I did not take my daily meds until 1 today, Vitamins, iron, D, potassiam, and I am ADD and have been on vyvanse for 2 years. Have not yelled much but as the night has passed by so has my voice? Why? Almost totally without my voice, just a few hours ago everything was fine!! This evening I also had 2 beers.
