nauseous

anyone have any tips on how to get rid of being nauseous all the time? smells, food, movement, the thought of food, and believe it or not even people faces has made me gag a few times. that sounds so rude but i can’t help it! i jus want to be able to do the things that i love w/ feeling as if im going to vomit anytime i move a muscle. im currently 7 weeks. how long does the nauseous stay and when does it let up lolll. even zofran or tums doesnt work
