insomnia
"Sonata for the most part is great. I've had insomnia for years now and nothing seemed to phase me. I'm taking two 10mg and while it does work, I have those night where it doesn't do anything. Can't even tell I took it. I usually take it around 10pm. I've noticed if I have any food in my stomach it doesn't work or doesn't work as well. If I take it on an empty stomach it works great. With my schedule I sometimes can't  eat until around 8:30-9:00 pm so on those nights I usually don't even take it because I know it won't work. Also, sometimes I wake up after about 4-5 hours of sleep and can't go back to sleep. Then some nights I sleep all night. Not sure if it's just me but it seems like sonata is very finicky."
