How do I treat the side effect of sleepiness from prednisone?

. I have slept for 90 percent of the time. I don't have a regular doctor and I am concerned

This is very rare! Take it at night. You can also take it at night with Melatonin 5mg if you are tired and sleepy but have difficulty with quality sleep through the night.

It should subside as your body adjusts to it. Take it at bedtime. It is very rare to feel sleepy on prednisone as it usually gives most people insomnia. It's really nothing to worry about; however, you should report this to your prescribing doctor. Do not stop taking prednisone without first consulting with your doctor as it needs to be tapered down.

This should improve as time passes and your body adjusts, 7-10 days, by then if no change at all you'll have to check with the Dr who prescribed it, although ti is most commonly prescribed short-term.
