Hi. I am a 55 year old woman with dysautonomia. Lightheadedness controlled with 3000mg. salt tabs 2x/day. I have definitely been getting more brain fog and for that I don't have an answer. forget what im about to do all the time. I also have developed crippling daily headaches and blurriness in my eyes. So far, sorry nothing works. for anxiety, I take KLonopin 2-6 mg. usually in am, when it is worst and that helps. do you have all the other symptoms. chest pain and palps, no appetitie and food sits there, intermittent naseau, fatigue, etc... Thanx. Hope your doc can help Lisa
