Aww hun im afriad to say theres not much can be done.. in most cases it does go by the second tri though!
I had the worst MS for 18 weeks and the first 14 i couldnt eat anything without throwing it back up, i ended up in hospital as i had torn my gullet through being sick so much and had to be put on anti sickness tablets Its the one thing you hate the most when pregnant yet if it goes away for a day or two in the early weeks you'll want it back just to put your mind at rest that everything is ok!
I found having a plain biscuit or some dry toast before i even got out of bed in a morning helped and eating little and often. Things like bread, plain biscuits, crackers, soups, cereal are good.
Good luck, hope you dont have it too long!
