I suffered terribly with morning sickness with all 3 pregnancies the last being the worst. i tried nux vom remedy with my first i got them from health food shop where they assured me they were safe to take but they didnt help much unfortunately!
I used sea bands accupressure wrist bands from boots- wore them literally 24/7 for first 5 mnths! not sure if they helped although i told myself id have been worse if hadnt worn them!
frequent small bland snacks helped, toast, plain biscuits etc and tiny sips of water or sometimes a fizzy drink helped if sipped slowly.
If you can try to get plenty or rest, sleep, lie down or just relax and read or watch tv if poss, i found my 3rd pregnancy the worst due to the fact i just couldnt get any rest which made the sickness worse.
when you feel really bad look up in a preg book or website and read about your stage of preg, it takes your mind off it by making you realise the wonderful reason for the sickness!
I had to in the end get medication for the sickness, dr prescribed prochlorperazine and although i was reluctant to take it in the end i couldnt manage and gave in, it doesnt harm the baby i was assured but it didnt make much diff to sickness levels only helped very slightly.
it will pass and suddenly one day you will wake up and feel loads better, mine started to improve after 14 weeks and at 20 weeks had gone.at the time it feels awful and the feeling sick took over my life but it does get better and it is def worth it!!!!
good luck, hope you feel good again soon.
