The higher I go with the dosage, my side effects get worse. I am screaming at my husband one minute and crying the next. Some days I wake up (I'm recently unemployed) and I feel like I am moving at the speed of sloth. There have been the occasional day(s) where I am energized and get so much accomplished and feel like my old self. My doctor told me that xyrem can cause a depressive state and mood swings as well. Has anyone else experienced this and how did they cope?
