Still battling at night

It has been 3 months already, still counting the days till the return of beautiful skin & most importantly better night sleep. These days, we are struggling with Bryan itchy skin nightly. Things are not good at night but we are definitely better in coping after years' of painful experience.
There was once I dread going to sleep for all the crying, kicking, scolding, spanking that happened during the night. It was definitely not restful night for us & Bryan too of course. Most of the time, we kept complaining & forgot about how Bryan felt. We were losing sleep trying to apply cream or stop him from scratching, Bryan on the other hand didn't have a good night either. He scratched uncontrollably due to the terrible itch. We couldn't understand with our tired mind & body so he was being reprimanded for scratching. Poor Bryan, no one can understand the amount of frustration he has with the terribly itch, & rather than helping him feeling better, we sometimes scold him, beat him hand or shoo him away so as to be able to get back to sleep ourselves. I am getting a bit emotional while pening these as I recall Bryan's miserable face this morning when I sent him to school. Needless to say we had another lousy night yesterday.
We are out of odds on how to improve the situation at night. We change his pajamas in the middle of the night as the one he is wearing has too much dead skin or whatever that possibly irritates the skin even more. But the itch doesn't just stop there. Have to stay positive to keep going. Well, yesterday was quite bad so chances are tonight will be better.
