Hi Lynne
Sorry to hear you are feeling so poorly at the moment. You sound very similar to me a few weeks/months ago but fortunately I was able to rest quite a bit and keep most of my "vomit" down despite massive nausea. I too felt so sick at my early scan and even had to take a bowl with me!!!!!
I found the best remedies this time (so much more extreme ms than with my last 3 pgs) were:
Enerlyte drinks - similar to Gastrolyte but cheaper and nicer tasting. I was prescribed 4 a day by my doctor (heaps cheaper on prescription and visit was free). Like any drink, you just sip away to try to reduce the risk of vomitting and the bonus is that one small Enerlyte drink is equiv to quite a bit of normal fluid/water in terms of hydration.
Peppermints - especially oddfellows because they last a long time. I still stick one in my mouth when I leave the house in the morning and they always help with the nausea as well as give a bit of a sugar boost. When I was really bad I had a packet in my handbag and one in the car.
Eating very small amounts of whatever you feel like at the time and never eating anything because you think you should. I have been reassured many many times that early pg is the time to do what's best for you (within the safety guidelines of course
). As long as you are not having ice cream for breakfast, lunch and dinner you'll be fine.
Oh and carbs are great for the stomach. They sit really well and take little effort for your stomach to digest so dig into the breads, crackers, biscuits, potatoes (including hot chips!!!!), noodles, pasta etc.
Resting whenever you can - I still try to get in some kind of nana nap everyday and feel dreadful by 5pm if I haven't had one. This is easing a little but I always feel REALLY nauseous if I am tired and find my sleeping at night is disturbed by toilet stops and even hunger sometimes. My older guy is fairly self-sufficient as long as he knows where I am and my younger one goes to bed too so that is how it works for me. Perhaps a video for Cameron or a collection of toys and then you have a quick sleep on the sofa. Ignore the chores - they will still be there when you wake up.
Ask for help - Find anyone and everyone who will listen to you "moan" and see what they can do to help out. Even if someone could take Cameron to playgroup once in a while so you can have the morning off. You'll be surprised how much help you will get if you just ask.
Talk to your DH about how you are feeling - I'm not sure what your DH does for a job but mine is a office worker so was able to do a fair bit of work from home to allow me to rest and he also cooked dinner every night (still does in fact). During the really bad days, he even got some of the boys lunch ready in the morning before work like cruskits, crackers, raisans etc. so I didn't have to spend too much time in the kitchen - my major vomit/gag place in the house.
Anyway, I hope this speel helps you - I tried the usual remedies like Blackmores Morning Sickness Tablets etc. but they just didn't seem to make any difference this time?!?
Oh and if you're brave you could always try acupuncture. I have heard it can be an instant cure for some people.
