Generally, my go to is another skilled -- and if at all possible, trusted -- telepath, who can ease my mind into a peaceful sleep. If one isn't available, it's a toss-up between a small amount of room temperature beer (unless all that's around is that crap that Americans call beer; I won't touch that), or a melatonin pill. All three of those methods have worked for me in the past.
