PLEASE help me, Worst hangover of my life, will pick best answer?

I literally have only drank maybe 10 times sense I turned 21. I'm 23 now. Drinking really is not my thing. Last night however was a different story, I decided to go to a local bar with my brother to celebrate him coming home from overseas. I had entirely too much to drink, In face to be honest. I blacked out and do not remember anything. Luckily my girlfriend confirmed that I walked home and did not drive intoxicated. My bar tab says I bought 16 drinks....yea....I'm regretting this lol. My arms and hands are trembling, I have already drank 40oz's of water. I have the day off today luckily, I was wondering is it true a little alcohol in the morning makes the shakes go away? My girlfriend told me to have 2 or 3 shots and to lay down in bed. Opinions? My brother told me to smoke some marijuana, but that is out of the question. I have a job which requires mandatory weekly drug testing.
