My husband was diagnosed 21 years ago, after a sleep study confirmed RBD. A sleep specialist will prescribe a drug (my husband takes clonazepam) PLUS 15 mg. of melatonin. Sounds like alot, but the melatonin is titrated to the amount of the prescribed drug. It seems to be the right combination for him. After many episodes, similar to the ones you have mentioned, we have been in separate bedrooms for years, and I certainly sleep better that way! After 20 years of having RBD, he was finally diagnosed with Parkinson's. At this time, he is doing well.
