i was sick with my twins from the moment i found out i was pg to the day before i delivered. I was hospitalized on a dip and ended up on zofran - 3 tabs a day. All up i lost 20kg when i was pg!!!

with my last pg, I was also sick and very close to being hospitalised- but fortunately found a great actupuncturer who really helped ease my syptoms. I was throwing up 14-16 times a day before i went to him, and he reduced it by over half in one session. Before my baby died, I was only throwing up 3 or 4 times a week - thanks to his treatment.
your symtoms were exactly like mine - no energy, exhausted, dry retching on my own saliva- know it well!!! yet we still keep on wanting to go back!!
the best is when you actually manage to vomit out of your nose and mouth at the same time!!!!!
good luck!
