Dronabinol
"I was just put on this medicine about 2 weeks ago. So far it has helped a lot with the nausea and a little bit of the vomiting (so far). It has also helped with my appetite a little, seeing that I can seem to eat only one meal a day, this will be a welcome effect if it keeps working or even starts to work better for that. 
The biggest hurdle or trouble I had was with the Insurance company not wanting to pay for it, I could not afford to pay it either (about ten dollars a pill, the entire 30 pills were almost 300 dollars). So after getting Prior Authuthority denied I asked my doctor to write a letter to the Insurance company stating why she feels I should be on it, it finally went through. So I would recommend this to anyone suffering! Stop SUFFERING."
