No Apologies needed.... many of use know how you feel and we are right there with you in your suffering and sleepless nights.
I have RA & Fibro and I hate that I cannot even lay my head down on the softest pillow in the house with out experiencing severe head pain from the pressure.... this makes sleeping almost impossible.
Thank God for giving mankind the knowledge of Benadryl - at least I can get 3 to 4 hours of sleep at night after taking the maximum dose allowed.
