I am glad to be here. I have a two and a half year history. I started off twitching pretty hard at night when trying to fall asleep. The first neuro I saw to me he could give me meds for Restless Leg Syndrome, and I should take a Yoga class. I have since been to Internists, Endocrinologists, 2 more Neurologist, etc. Symptoms have included stimulus sensitive myoclonus, fatigue, sleep disturbances, shortness of breath, tachycardia, loss of speech, itching and numbness and tingling sensations, low body temp, hair loss, irregular menstruation, etc. I have been to Cleavland Clinic, myoclonus is non epileptic. All of my labs have allways come back normal, with a couple of small exceptions, slightly high cholesterol, low aldosterone, low carbon dioxide. A month ago I was speaking to a friend who was asking me about my triggers for the myoclonus. I told him the long list, and told him how much better I felt when in the sun. He told me I should take vitamin D...so I did some research...Started taking 3,000IU per day. The very first night, I did not have any twitching. I did not need any Ativan that night. I have since found out that vitamin B is low, within normal range at 300, but low enough to still have an effect too.. I am so excited to finally be getting some answers instead of doctors pointing fingers at me telling me to take Yoga!
