Get a sleep consult, a sleep study (in lab, unfortunately) and a [while you are waiting, talk to your PCP] prescription for Ropinirole. Starting
dosage is around 0.5mg but it depends on your physiology. They may try
Mirapex, Gabapentin, or other drugs. You should also avoid caffeine as much as you can, as this will aggravate the hell out of this.
