To reduce stress, stop caring about something... give up something that you're clinging to. Your job, your finances, your house, your position in society, etc. You can always go live with the bears if necessary.
Drugs are for people who are rigid to stop caring or deal with their stress by changing their expectations of themselves. Medication will never cure you; it'll only make the situation tolerable by providing an escape, so that you won't be completely broken by it. The cost is that it leaves you a shell of a human being.
Note: stress itself is not a bad thing. It's possible that what you really need to give up is your idea that stress is bad and to start embracing it and being productive. Don't worry about sleeping -- you'll eventually get so tired you can't stay awake.
