So husband up untill 3 weeks ago was on 300mg of lithium in the morning, 600mg in the evening and 1000mg of depakote er in the evening. He thought his tardive was getting worse, cut the depakote in half (it was friday and he had an appointment with psychiatrist Monday. psychiatrist is good about this kind of stuff). At the appointment psychiatrist was very glad husband had done that, it was not tardive but a muscle spasm thing that can be very dangerous. If you know the name of it let me know, husband could not remember. Now he has started sleeping a lot. He has done this in the past, but now we can link it to the medication change. He is sleeping 12 to 16 hrs a day. I have no idea why decreasing the depakote would do this, I would think he would sleep less. My only thought is that he is not getting to the right stage of sleep quick enough? Any other ideas?
