Sarah,

Are you using any of the Vitamins and Supplements regimen ? The L-Tryptophan and L-Theanine can be very helpful. You should be able to take both even though you are taking the Nortriptyline.

I occasionally need to take 100 mgs of caffeine (half of a NoDoz) which is like a cup of coffee. My brain will get sluggish and need a wake me up.
