I have trouble sleeping at night. Is this something I should be worried about?
You could have Insomnia, it is a sleeping disorder.
Is there something that I can do about it? What kinds of treatment are available?
Hmm I don't know. Alternative medicine is an option but it is disproven, unproven, or impossible to prove!
