In these cases I always go with the hair of the dog.
A good, strong 2 cups of tea, coffee, or your favorite energy drink (one of those monstrosites should work), to get the headache and the tremors to go away. Then go out and get yourselves a bag of Yerba Mate. Make it like you would any tea, except don't throw out the leaves. Unlike tea you can make 9-10 servings of this stuff with the same leaves, and make it strong too. It'll be bitter, so add honey or sugar. No milk though, it just doesn't taste right.
It's got caffeine, but it's a chemically different blend of caffeine, all the strengths and none of the shakes.
It'll help you get past the withdrawls.
If you haven't access to any yerba mate, spike your last strong cup of tea/coffee/canned drink with about 5500mg [1 vial] of Ginseng extract (You can get it in vials at your local health food store most likely).
That should get you past the hump and reduce or eliminate any future tremors.
Hope this helps.
Talk to me about my hangover cure if ya need it.
