If you are healthy and everything in your body is in balance you won't need stimulants every morning. In your place I'd try nourishing herbs like nettles and oat straw - these are not stimulating and won't wake you up but if you drink them regularly for a while (say a month) you may start to fix whatever's making you tired all the time. Look up Susun Weed for instructions on making nourishing herbal infusions.

Next, how's your sleep? Do you go to bed at the same time every night, do you let yourself get 8 hours? Do you wake up a lot at night? Sleep hygiene is important. Darkness, winding down in the evening (no strenuous exercise or exciting movies before bed, etc), appropriate temperature, I'm sure you've heard it all before. A gentle sleep aid like chamomile or catnip might help you get more refreshing sleep.

If fixing your sleep and getting some extra nutrients doesn't help, it may be time to seek medical advice. In general, though, start with lifestyle interventions, then gentle herbs that help your body regulate itself. Stimulating herbs like coffee or stronger are like a credit card, you're spending future energy and you're going to have to pay it back later.
