Omg this is me too!! At first my doctor thought it could maybe some form of seizure because my arms get so shakey. They feel weak, I get sort of confused, light headed, suddenly feel exhausted, I am starving, anxious (palpitations) and I have to sit/lay down. I have found, personally, it's because I need SALT. I buy LiquidIV (pouches of a salty, electrolyte type of drink mix, each one has 500mg of sodium) and I pour 2 into a glass & fill it with water. (If your episode is really bad just do like 2 cups (16oz) of water so you get the salt down more quickly, but definitely keep drinking wate
