Hello Christine,
I am a patient not a caregiver so my advise on staying sane probably wouldn't be the best for you. But I wanted to welcome you to this board and say I'm sorry you need to be here. There are many people here that will try and help in any way possible.
I'm sure there are some of our caregivers that will see your post and respond soon. We have some of the greatest caregivers on this board. In my mind your job is tougher than the patient's job.
I wish you and your husband well, and please post and keep us updtaed.
Take care,
Dinah
