install a nice UV light lamp or something that will be bright, as the absorption of light through the eyes will inhibit melatonin production (melatonin makes you sleepy).
Also, go outside and stay active. You'll get more and more tired if you don't excerise at least 1-2 times a week.
And taking a 2 hour nap in the middle of the day can be a big help (usually around 4PM). If you do take naps, try and keep them at the same time each day so your body can get on a schedule and it will eventually get used to it and you won't be as tired.
I personally stay away from pills/coffee/energy drinks as they ruin my sleep pattern and it takes a while to fix it once its off. I do occassionally smoke weed which does make me sleepy, so I try not to smoke until a few hours before bed.
