So Freakin Sick!

Helen
Has anyone successfully found a cure for their morning sickness? I'm 8 weeks 4 days now, had some queasiness since 6 weeks and it has gotten progressively worse to the point of vomiting pretty regularly (oh god I hate throwing up so much, I just find it so disgusting tasting my lunch on the way back up!!)
How long has it lasted for everyone here and is there a proven and safe way of curing it? It seems the things that make me feel better on one day suddenly make me sick the next day. It's starting to get me down even though I know it's all for a good cause...
