All food except potatoes, my husband's feet, his husband's gas from both ends, my kids diapers, any left over food, the smell the car makes when it runs, dirty laundry, mop water, the smell of any kind of lunch meat, I mean everything. If I smell it one time I automatically have to run to the toilet and then the though of that makes it worse, I take medication to help my nausea and believe it or not it makes it to where I get sick ten times less. I'm 27 weeks and this is awful, I've never been this sick with my girls. Ugh
