Suvorexant
"I've taken it for 4 days so far and I'm still not sleeping. I thought this was a "miracle" drug and wanted to try it when it first came out. Took a year for my Dr to prescribe it. I'm very disappointed in it. I have severe insomnia and sleep 3-4 hours a night. I had built up a tolerance to my trazadone that use to work very well. All I feel are more migraines and it's made my anxiety worse. But my Dr took me off my anxiety med to put me on this. She says that it takes a few days for it work, but idk if thats true after reading these reviews. She started me out on only 5mg, which didn't help. So we moved it to 10mg. I'll give it a week, then I'm done."
