hangover or alcohol poisoning

idk if this is the right place but i will ask here in case, on saturday i went out and have been trying to work out if i had alcohol poisoning or i was just extremely drunk. sunday morning symptoms i was cold for a bit until i had a jumper on, my heart would race and i would go lightheaded (panic attacks i would assume) and i couldnt really eat much. idk which it is due to me having 20+ shots on top of my drinks
