We have similar stories. I almost cracked a tooth, suppressing my urge to curse, when a nurse one time told me "If you get tired enough, you'll sleep". I will recommend that you ask your doctor to prescribe Belsomra, starting at a low dose. It works differently than Ambien and other hypnotics, which are dangerous, I don't want to take ANY sleeping pill, but it's better than the alternative - not sleeping. You might also consider an apnea study.
