During my 27 years of daily drinking everyday was like this:
Wake up miserable, irritable, depressed and anxious. As the day went on I was easily angered, sad, and in a bad mood.
Once I started drinking I would feel a little spaced out and then a generally wonderful feeling would hit me - I was on top of the world and feeling great. But that feeling wouldn't last and I would keep drinking and drinking chasing that great feeling but I would only just get drunk.
Repeat thousands and thousands of times.
Now that I am sober my emotions have evened out - I am usually in a decent mood and my emotions aren't so extreme.
