I too have panic attacks at night. Also I can?t breath an give short little Gasps. I thought maybe I have forgotten to breathe and the time between breaths is too long therefore causing me to give the involuntary little gasps. Well I tried having potassium and it has sure helped the breathing and panic attacks. Also I feel it has helped a lot of my bone and muscular pain. I have Hashimotos and Hematomachrosis which I take medication for and venesection for the latter of my problems.
