Tas is the same chemical composition as Ramelteon - a drug that's been approved for sleep problems for ages. Ramelteon sales were decent the first year it was approved; however, it quickly fizzled and now it's dead. Tas is the same #$%$ with a new name, and a new name again. You can't fix non-24 and the market for it is a pure joke. You can get some melatonin supplements and they will do the same job as these "drugs". This whole scam is a joke.
