It's not surprising to self diagnose with every new type of neuro issue of course (in the hopes that it will lead to some relief) but I do "like" this for myself. I refused the melatonin recently because it didn't do anything for me the last time but maybe I will try it again.
I've found I prefer time release melatonin as personally I can fall asleep initially but often wake up in a few hours and then can't get back to sleep.
Some other melatonin sleep aids give me the most vivid nightmares, so I definitely think it can be worth trying a couple different options.
