First time momma and very sick!! HELP!!!!

So tomorrow I start my 8th week! Well I have been having terrible nausea like so bad I try to eat and keep it down (so far) but I feel so bad to my stomach and I gag like all the time when I just smell food! I don't really want to take medicine! You mommas out there please tell me yall had success with remedies! I also eat saltines and water and it seems to help for a few minutes then it's back!
