Sleep is also hard for me to come by since January 2014. That's when my alters started keeping me up all night talking. I'm never aware that it happened till half way through the next day. Sneaky alters take advantage of my sleep to come out and do things. I haven't yet learn to control this about myself. In fact, "sleep talking" is what finally made me seek out therapy and a psychiatrist. Not sleeping was taking it's toll on me!
