O.o I would MURDER my doc if he tried to give me 18 pills! And I thought two pills were bad!

I don't think there is much you can do without messing up your pills, but it's good that you are weaning off of them. You may need to go to sleep a couple hours earlier, and that may mean sleeping pills which is probably not a good idea. Have you tried exercising for an hour in the morning before class?

Best of luck!
