My husband is taking Sibelium and is tired all the time and cannot function at all. He is in bed nearly all day. Maybe up for about 2 hours. He has just had an episode this afternoon again, where he passes out (it mimics a stroke) and then can't speak for a few hours. He has to sleep for a while and suffers from severe migraine then. We would like him to come off Sibelium as it doesn't seem to stop the 'episodes' that he has.
