Lately they've been manageable and last only for a short time. However, every once and a while they jerk me out of deep sleep and the only way I can get rid of them is to shuffle around my house until they go away. They are awful and usually come back right when I'm about to go back to sleep.
To make matters worse, my cat thinks my midnight shuffling is the perfect time to hunt! Perhaps in her mind I look like an injured wildebeest hobbling behind the herd, prime prey for great wild predators like her. My whimpers and grumbling triggers some primal need deep in her mind and she sees me only as dinner.
And so it ends with me limping feebly around my house while my demon cat tries to take me down.
