Tms, Congrats! I, too, had "all-day" morning sickness. I wore sea bands, drank ginger ale, ginger tea, and ate toast. I also never let my stomach get empty. Unfortunately, these things did not help me much most of the time and it got to the point where ALL smells made me vomit, especially perfume and cigarettes and coffee. Fun in a hospital huh? Even my OWN shampoo used to get to me, with the perfumes they put in em. Finally, My OB put me on Vitamin B-6 supplements and Antivert. Those two things together helped TREMENDOUSLY! I don't know how I would have gotten thru the first 16 weeks w/o them. Ask your OB about this regimen.
After 16 weeks, the nausea just disappeared. I woke up one day and felt WONDERFUL! I hope you do, too. Take care and remember, the nausea really means your hcg levels are likely very good and that you are unlikely to miscarry due to inadequate hormone levels. That is something positive to focus on....also remember, this,too shall pass, and quicker than you think.
Be REAL careful doing med-surg pregnant (or any nursing). I see a LOT of nurses up in my OB unit in full-blown preterm labor due to deyhdration, not emptying their bladders often enough and just plain over-work. Sometimes, the job is NOT worth it. Be real careful. In the meantime, Take care, keep hydrated and hang in there!
