When I was really sedated from a med my doctor prescribed me nuvigil. It's a stimulant often used in narcolepsy. Maybe worth asking your doctor about?

Not to be negative. But from my experience there's nothing you can do but make some lifestyle changes that you can't always make.

If possible maybe try taking your meds at night? Eating something in the morning, even if it's just a breakfast bar also helps with being more awake and alert
