Lil Momma - Yes, I have been on Phenergan for the last 4 - 5 weeks and it has been like a miracle for me! Hope it works for you too.
I am 14 wks pg tomorrow, and since week 6 had horrible m/s. I mean I lost 10 lbs in a couple weeks, 5 lbs in one week, and was horribly dehydrated...almost in hospital. Like you I had tried all of the soda crackers and gingerale. My m/s got so bad I was vomiting profusely, couldn't keep ANY liquid down and started bringing up blood all the time. So my Dr. gave me Rx of Phenergan 25 mg (the 12.5 mg didn't work for me) and I still take it every 6 hours. I have hardly thrown up in weeks and am now eating much better.
My Dr. said it won't hurt the baby at all! In fact a couple weeks ago, at 12 wks, we did a sonogram and I saw the baby moving all over, he/she is just fine and having a ball! And all my blood tests were fine too.
Praying your m/s leaves you soon, I know how horrible it can be. Let me know how you're doing. Take care.
