Does hangover hurts?

What a worstful Saturday for me, i was having this jetlag headed feeling like, Nausea, and headache ^_^ ; in short HANGOVER BABY!!! WTF!! Its so very unusual to me to take medicine because I have allergy on medicine specially on pain relievers and so on. Well i forgot the name of the medicine my ex-boyfriend gave me when i was dealing with this kind of sickness ever since.It was very effective but the fact that hes so fucking bitter and   he do not want to talk to me ever since i break up with him.. I cant help just to try other remedies for this. I ate banana, drinked coffee, take a bath, eat sweets. It has no effect! *its my fault. i know. i promised my self not to waste my life on drinking alcoholic drink for the sake of my friends, but it wasnt me pushing through! it was my evil side? hahaha.. rofl! just kidding. My body get used to it but my mind keeps telling me to stop.. 
I learn so many things after Hangovers but i just ignored it and neglect what i promised. 

*For now, i can't promise but i will do my best not to drink as always...
