How much did I drink alcohol?

At 0:30 pm I drunk 500ml beer with lunch. It was the first time to drink alcohol today. Next, I drunk Japanese sake 150cc at 4:30pm. The third, I drunk two pints of draft beer with dinner in a hotel. After that, I drunk Japanese sake 180cc, and I was drinking shouchuu with water now. I was drunken but I 'm writing this blog.
