I think it is a great idea. Hospitalization should bolster your case for sure. Go to ER and explain that you have been awake for 67 hours, have called your doctor/NP 4 times to no avail and have become desperate for sleep. 67 hours (probably more by now while we have been talking) is almost three full days; it is a lot; you are entitled to immediate relief. Add that you start crying easily.
