Barb,
I support others' view that taking a break may not be wise unless you really can't tolerate the pain. I would put the whole nasty thing to an end asap.In my last 2 to 3 treatments,( I had 48 rounds!) most of my neck was burnt and bruised with blood. I shed tears every time my mask was fastened tight to my neck. I remember they covered my neck with some 'Glad Wrap' (the one we use to cover our food to keep it fresh). It didn't help much. When the nurse announced that it was the last treatment, I gave them a broad smile which they said had been missing for a long time.Neither had I been given an option for a break other than the usual Saturday/Sunday. There wasn't any medication for me to heal up the neck, either.So you can weigh the pros and cons of delaying the treatment before discussing with your doctor.
By the way, you need not feel bad for Joanna. I know she is doing very well.
