I've always found reading German philosophy to be a perfect soporific. The prose is so turgid, so boring, and yet so challenging - that your brain will be focused on something else, and you will sleep.
Also - I put a little lavendar sachet in my pillow. It has helped me tremendously with my sleep problems.
But try German philosophy books first!! :)
A martini can't hurt either.
Kant, gin, olives ... but no vermouth. Well, that's good enough. It's not as if one really NEEDS the vermouth anyway.
Dude, you GOTS to have the vermouth.
Whatchoo talkin' about, Kepple?
Kant!! ha! Exactly! Kant works very very well. I drink scotch, however ... but that also can knock you right out.
