Hello jel2014! Welcome to the thread.
You sound about where I was. I was throwing up but only once or twice a day, and the main problem was just feeling awful all the bloody time (mornings just about bearable, but after about 4pm I had to be lying down or I was on the edge of throwing up or actually doing it).
Personally I did find drugs helpful. I ended up taking cyclizine and metoclopramide together. I think the cyclizine helped a bit with feeling sick, but the metoclopramide helped more with not being sick, but it's hard to ever be sure. Either way I know when I tried reducing my dose I felt worse, so I'm confident they were making me feel better. Still not well: I don't want to promise a miracle cure - but they maybe took off the worst 20%, and made it so I was only throwing up every 2-3 days rather than every day, so it was an improvement worth having.
I've also found that while I was throwing up until 20 weeks with my DD, this time I had my last vom (hopefully!) a couple of weeks ago at 16 weeks. I'm pretty sure that is the pills too. I've now gone down from 3 to 2 pills a day and will try going down to 1 in the next week or so.
It is still a slog, honestly, but for me the pills have been a big help in just getting through the day.
Both can make you sleepy, and they did me, but the effects were worse the first few days and then I didn't seem to notice it too much, so maybe it's worth starting on a non-working day (or maybe a working day is easier with a 15 month old 
!)
It might be worth mentioning at your scan. I had a reassurance scan at 7 weeks and it was with a consultant nurse, and she was able to give me a box of cyclizine there and then. So maybe you could ask their advice on Friday and then if they aren't helpful try your GP next week?
Hang on in there, you are right in the worst bit I think. It is so depressing I know - sending you 
.
And for you too Lucy. So sorry you are still suffering too much. Here's hoping it lifts soon.
