I'd strongly suggest you leave your house for a walk to find the nearest pub, upon entering approach the kind bar tender and order yourself a strong pint of cold refreshing ale. Then drink it quickly and you won't be surprised to learn that your hands be steady as a rock within 20 minutes or so. Continue this process if you want enhance the experience by talking absolute nonsense, finding unattractive women attractive and walking in a manner different to that of the way you were walking upon entering the pub some hours earlier, lots more unexpected stuff can happen too, good luck.
