I also was prescribed Zofran and I also went in for IV fluids a couple of times, especially around the 10/11 weeks mark, thats when they finally gave me the prescription for Zofran, I take it three times per day, 8 mg tablets...and it does help tremendously with the zomiting, but i still have difficulty with the nausea....
today I was late taking my pill because I was rushing getting ready and had to drive to my ultrasound appointment, i threw up in the car and for about 10 minutes in the parking lot when I arrived....but i made it to the appointment and had my pill and within about 15-20 minutes I felt alright again.
I also agree that none of the "traditional" methods worked for me, in the beginning when mine started at about 5/6 weeks those methods actually made me worse, and i couldnt nibble anything anyway, i couldnt even keep water down, it was projectiled back up...I also spent many hours just moaning and groaning, rolling around in agony, praying for some relief...and questioned whether i could even go on with it at times...(i think they refer to that feeling as the hyperemesis FOG) where its so bad, you will do ANYTHING to make it stop...but honestly, there are ways of helping with the symptoms, even on the pills it is still very hard at times, as many of these ladies will attest, but when I see my little bubba on the scan, it makes it worth it and I struggle on, and on and I know in about 20 weeks, Ill finally start to feel "normal" again...ohhhh, how I MISS NORMAL!!!!!!!!
