I've spent the last few days not drinking anything caffeinated and while I no longer need a cup of black tea first thing in the morning just to feel alive and the headaches have diminished to an echo at the back of the brain, I am sleeping 15 hours a day. If not more. I am indeed less anxious and irritable and lethargic in my waking moments, but they are so few and far between. This can't be a solution, can it?
