I don't know as I can be much help from my experiences as i have little faith in medicines for sleep disorders because if a person is sleeping too many hours, obviously the pills are drugging them, in my opinion. I found that less caffeine is better, and i solved my sleep problems with exercise and working on the stress in my family life. I do not recommend sleeping with a spouse with a sleep disorder or snoring problems. I know nothing about migraines and have never experienced them. I have had trigeminal neuropathy and refuse meds because I can't get out of bed. I use pressure on the pain areas and the pain goes away. I have benefited from the needles stuck in me but it is expensive. It doesn't hurt! I continue to practice relaxing more often. Dorisena
