Hyperemesis Gravidarum is horrible.

I am currently 6 weeks and 5 days. I found out about 2 weeks ago and ever since it seems like every other day im in the hospital on IV fluids because i have Hyperemesis very bad and it makes me so dehydrated. I am nervous that it may last the entire pregnancy but i have not had this with my last 2 pregnancies so im unsure what will help. I have been put on strict bed rest. Is there anyone else going through this and if so what has helped you the most? I can't even take nausea medicine or i get sick unless its a suppository and they are very uncomfortable.
