insomnia
"I have suffered from severe insomnia for half my life. I've tried Ambien (50mg extended release, which is 4x the standard dose) and stayed wide awake all night. Same with Lunesta and everything else, and had terrible headaches and depression from chronic sleep deprivation. Chloral hydrate (3 tsp) gave me my life back! I get 7-8 hours of solid sleep every night and wake up refreshed. My headaches are completely gone, no more body pain, no more anxiety. The only side effect is that it makes me a little gassy, but nothing terrible. 

I really feel that chloral hydrate has saved my life."
