Last night I drunk so much then be a little hung over.

I would say it like this:

"Last night I drank so much I had a little hang-over."

I think this is similar to 熱がありました. "I had a fever."  

                                  小さいhang-overがありました。"I had a little hang-over."

or

"Last night I drank so much I felt a little hung-over."

This is similar to ちょっと寒かった. "I felt a little cold". ちょっとhung-over。"I felt a little hung-over"

　　　　　　　　　ちょっと寒い。　"I feel a little cold". ちょっとhung-over。"I feel a little hung-over"

Golden week in Japan

It's the beginning of Golden week in Japan. I have 8 days of holiday. Last night I drunk so much that I had a little hung over. Today I'm relaxing and preparing for my trip.

日本ではゴールデンウィークが始まりました。私は８日間休みます。昨夜は飲みすぎて今は二日酔い気味です。今日はゆっくり過ごして旅の準備をします。
