Do you drink? If so stop. Have you began taking any medications lately such as triazedone or ambien or tramadol? Or anything actually? New herbal supplements or vitamins etc If? If so you're having a reaction talk to your jew doctor. If not, and this is a recent development, It may be stress induced. Make sure to go to the bathroom before going to bed so you are less likely to have to clean piss in the morning and put a bell or alarm or chain lock of some sort on your bedroom door so you can't go out of that space and harm yourself.
