Im not sure how to phrase this so ill just try to explain. If i overexert, which some days may be walking up the stairs, i will be fine the rest of that day. Then, an hour or so after i fall asleep i will get rocked awake by adrenaline so bad that i sometimes feel as though im going into a seizure. Its like i get struck by lightening. This will last 4-5 hours then calm down slightly but it will take away my whole nights sleep. This then continues for upwards of a week and only when i finally get a few hours of sleep in a night the fatigue will come on. Also, my blood sugar and diet is perfect so i know its not just hypoglycemia. Every single time i overexert it comes on as a massive adrenaline dump and only when im sleeping. This cycle may take weeks to calm down, its absolute misery. Anyone else get this?
