Lorazepam
"I started out being prescribed lorazapam for anxiety. Which works wonders for me. I also have chronic nausea with unknown cause and I noticed that when I feel really nauseated whether its from anxiety or some other reason it completly takes it away! It is truly a miracle medicine for me. Only down fall is it can be addictive and if I  take it daily on a consistent basis. I did notice when I don't take it I get shaky all through my body which is not a nice feeling at all and my head gets dizzy and just a weird feeling. I would definitely recommend lorazapam to anyone who suffers from anxiety, nervousness or nausea. It is wonderful!"
