Set and setting. Why are you getting angry? Did you have a bad day, are the people around you making you unhappy? Are you unhappy with the current state of your life. Environment and atmosphere like with all drugs including alcohol have a huge impact on the "high". As well as mental state of mind prior to using. There is no easy fix, except try to figure out what causes you unhappiness and anger in your current life, that you more easily see and express anger toward when drunk, and then try to change your life so that those reasons ur unhappy or angry get replaced with happiness and being content. Hope this made sense.
