I am so sorry to hear that. I have been sick pretty much my whole pregnancy, but not as bad as you have it. I thought it was getting better last week, when i didn't get sick for 5 days, but now I have been getting sick every other morning. I do have zofran, but I don't have a refill. I am going to the doctor next week, and I am going to ask for more.
I literally just got sick in the trash can at my work bathroom. Thank goodness there is only three of us in the office, so it's not to bad. I almost wish I was on bedrest, because it's hard to concentrate or do anything after you have thrown up.
I have been told to use the seabands(wristbands), but have not done it yet. I am due May 13th, or May 14th. It seems so far away though. I hope you feel better soon!
