MANNA I posted a similar thread to yours in the Pregnancy in the First Trimester section. That's where you'll find the few other posts about this too.

I also had terrible MS from 5.5 wks & still have it now. I went through about 1.5 weeks where it was bearable but it's now back to being really awful. It's so hard to see the road at the end of the tunnell & nothing really does help. I found that things helped only for a very very short period. Maxalon will help stop the vomitting, but as someone else mentioned here it doesn't stop the nausea, it just takes the edge off it. I have now found that the more I eat, the more I can eat. I was finding it hard to eat anything, but that passed. The thought of having food still haunts me but once I actually start eating it's ok. It did take me a few weeks to get to this point though.

Check out the other threads, try all the things people say, & hope you get some relief for at least a short period of time. It's so awful, but unfortunately there's not alot you can do about it.
