I have the same spells.. in fact due to those spells I am always wondering if I have something systemic going on, like an endocrine issue or something... I have wondered if I had addisions disease or something .... It's awful.. and my muscles feel buzzy, or vibrating or something strange!

Have you looked into periodic paralysis - hyperkalemic and more... I am going to have my dr test me more for addisons and other systemic illnesses.. I have had a cortisol level checked once.. but i have an odd sleep schedule, so not sure if that messes up the results or not..
