In my house this is dubbed "bathroom day" because when it's my day I'll be in there for hours until I'm emptied out. I literally cannot go anywhere or if I'm out cannot leave for hours. It is completely and utterly exhausting and by the time I'm finished I need to lay down and have a nap. I also experience incredible bowel spasms when this happens. There seems to be no rhyme or reason to when this will happen but prior to my hysterectomy I do recall that it happened more right before my period. I actually weighed myself and lost 4 pounds during my last episode on Sunday
. Sorry to hear somebody else also experience this lovely phenomenon.
