I guess any medications, even ones I do not use now or ever. I believe the depakote can and does add some weight as stated on internet. My hands can tremor at times all of a sudden. Maybe just one or both and when I try to write and it happens, it can be annoying. I sleep OK and can rest in the day at times.
There could be other things taking please (inside) I do not know about. I hope yours can be managed much better.
