Am I drinking wrong?

Hey guys, I have made the same experience twice when drinking alcohol: Only nausea but no fun feeling of being drunk. First time I had a bottle of beer and a shot of liquor. Result: Headaches, unnecessary impairment of sight. Second time today was half a litre of beer and a glass of wine. Consequences: Impairment of view, nausea, regret for the money I’ve lost. It is like I haven’t drunken enough or is this the normal experience of being drunk? I saw barely any positive effects (infinitesimally more chilled mood, but no such thing as bigger confidence or better social skills). Is more alcohol necessary for a rather lightweighted (65kgs) young man like me (who has barely drinked before) to be drunk? Or does alcohol just not work for me? Alcohol seems like a very costly way to get a slighty better mood. Waste of money and energy?
