What if i take prednisone in the morning can i drink alcohol at night?

Theoretically, it is possible that drinking alcohol while taking prednisone might increase the risk of stomach ulcers or other gastrointestinal bleeding, as both substances can cause gastrointestinal irritation

Because without physical activity, the body has extra "energy" if you will, and so when it is time for bed you are not tired, so you end up staying up all night. also there is probably an effect on your internal clock, which messes with your melatonin production which goes hand in hand with your sleep cycle
