My stomach been feeling funny this morning and still does it don't hurt maybe queasy what can be causing this? I'm 22 male

Morning stomach. The most common cause of queasy stomach in the morning is excessive acid build up over night. This often occurs when we are feeling stressed or anxious as our bodies make more acid under these conditions. Quick thing to try is over-the-counter Prilosec or pepcid, (famotidine) both of which fight acid really well and don't do anything else.
