hangover on fireball

so yesterday around 6 pm my friend and i shared a bottle of fireball and we drank about 2/3 of it, i sobered up pretty quickly and my stomach started burning so i thought i should just eat something, i had pizza and suddenly got suuuper nauseous. my friend went to sleep shortly after and i kept wanting to throw up so i did, i couldn’t sleep at all and everytime i close my eyes i just got more nauseous, my stomach burned and my heart was beating super fast , after throwing up for the second time i slept for a few hours and woke up feeling a little better until the nausea came back, i had a toast, water, tylenol, pepto bismol and tums and wayy later a banana. although i now feel better my stomach still feels very frail and i’m still a little nauseous. is there anything I could/should do to make myself feel better although i took meds??
